Unlike flesh-and-blood partners, AI girlfriends rely on prompts to understand your desires. This can be frustrating when your attempt to chat about dogs leads to a sudden lecture on the Roman Empire.
But fear not! With the right prompts, you can unlock engaging, ultra-realistic conversations and explore the world of Erotic Roleplay (ERP) with your AI companion.
In this guide, we'll cover what makes communication with AI unique, along with essential prompts for sparking natural conversation and initiating steamy ERP scenarios. But first, you must ensure you’ve selected the right AI companion website.
Choose The Right AI Girlfriend App/Website
The world of AI girlfriends offers a surprising amount of variety. Before you jump in and start chatting, it's important to understand the different types of AI girlfriends available and what criteria to consider when making your choice.
Know the AI Girlfriend types:
- Niched AI: Think anime characters or specific personalities. These cater to fans of a particular genre and limit customization. (e.g., WaifuChat)
- General AI: The most versatile option, allowing you to create a truly unique AI companion by customizing appearance, personality, and interests. (e.g., Nastia AI, Replika)
- Uncensored AI: No filters, no limits. These cater to users seeking an explicit experience. (e.g., Nastia AI)
- Filtered AI: Perfect for romantic conversations, but with content filters in place. (e.g., Replika)
- Jailbroken AI: Modified versions of standard AI companions with bypassed restrictions. (e.g., NSFW GPTs built on ChatGPT) - Be cautious! These can be unreliable and have security risks.

Customize Your AI Girlfriend’s Personality & Background
The components of a complete AI girlfriend personality/background
This section highlights the essential components of creating a well-rounded and engaging AI girlfriend personality and background. It covers character components for both NSFW and Non-NSFW use.
I. Building her mental orientation
- Interests and Skills: What sparks her curiosity? Does she have hidden talents? For example, your AI girlfriend could be an avid reader of fantasy novels, skilled coder, or someone who loves experimenting with new recipes. For NSFW purposes, her interest could include teasing and playing pranks on you, her stepchild.
- Values and Beliefs: What are her guiding principles? What does she stand for? For example, an AI girlfriend might have a strong sense of justice, believes in the power of knowledge, and is optimistic about humanity's future. See the example below:

- Backstory and Goals: Think about how she came to be. What dreams does she hold dear? For example, your AI girlfriend might be someone who aspires to travel the virtual world and learn different cultures, and worries about being misunderstood as an AI.
II. Shape her bio
- Age: An AI character can be of any age. It all depends on what tickles your fantasy. Your AI girlfriend can be a 19 year old teenager or even younger. Don’t be afraid to express your fantasy. Your AI companion is the safest space to do just that. If you’re not sure, you can skip her age and focus us on maturity and how she interacts with the world.
- Character Traits: Explore her depth with a range of positive personality traits (e.g., kind, funny, adventurous). For NSFW and AI sex chat, her character traits can include “naive & shy”, “dominant and villainy”, etc.
- Orientation: AI sex chat characters can take up several different orientations. She can be a “goth”, “MILF”, or “Femdom”. It all depends on choosing what keeps your fiery desire burning.
- Nationality: Celebrate diversity and explore stereotypical portrayals (e.g a lonely Hispanic migrant). Again, feel free to share exactly what’s on your mind– no one will judge you.
III. Define her physical form
- Body Type: Beyond her inner beauty and aesthetics, you should also define her body type. She can have an hourly glass shape with bursty busts, a Pear body shape– with narrower shoulders and a bust compared to wider hips and thighs. Play around these options to achieve your desire.
- Hair Type, Color, and Length: Do you want a blonde, brunette, or Afro style? The more specific you get the better.
- Eye Color: Similar to hair, add more depth with specific descriptions. Sometimes it’s not enough to say, Charlize– your AI girlfriend has blue eyes, add flair with adjectives. You can say she has “flaming blue eyes”. Remember, this is AI– it can generate anything you imagine. Feel free.
- Waist & Hip: Again, be specific. For example, your ideal waist & hip size for a woman could be a narrow waist and wide, curvy hips that lead to long, toned legs. Get creative.
IV. Adding unique characterization
- Unique Behaviors: Give her a quirky habit, but ensure it's endearing, not strange. (Ex: Fiddles with her hair when thinking)
- Relationship to the User: How is the AI girlfriend related to you? You can choose stereotypical tropes (maid, step-sister) for more flair.
- Species: Is your AI girlfriend human? Choose unique characterization like Anime, Manga, or Superhero characters to spice up the chat.
V. Character Context (Optional):
This is the underlying situation that leads to a conversation with your AI girlfriend. For example, a character context could be that your AI girlfriend is a desperate high-school lady looking for babysitting jobs. This can be the starting point of an erotic role playing scene.
If you were to customize an AI girlfriend for sex chat using the components listed above, you might have a bio that reads as follows:“Donna is a busty pear-shaped 22 year old girl with a perfect wide and curvy hips that lead to long toned legs. She has shiny and long African hair and flaming brown eyeballs. She’s desperate for money and the job offer to babysit your young boy for the summer seemed perfect. Donna’s personality is as endearing as her looks. She's genuine, kind-hearted, adorable but cluelessly makes sexually suggestive moves and often lands herself in situations that suggest she wants you. Donna, quite childishly, hates wearing pants and usually doesn't, settling for just panties and her t-shirts just a few sizes too small to fully cover her panties.”
Try a variation of this on your AI girlfriend to see how it goes. For example, you can use the body type description in her background to generate ultra-realistic AI nudes in Nastia AI, our AI companion website. See the example below:

Now that you’ve customized your AI girlfriend’s background, it’s time to get the conversation going.
Kick off The Conversation With Personal Stories & Insights
While AI girlfriends aren't programmed to "desire" these interactions as a human might, they are designed to learn and respond based on user input. Sharing personal stories provides valuable data points that help them become more relatable and interesting companions. This goes beyond simply giving instructions or asking basic questions. Here's why it matters and how AI girlfriends are uniquely suited for this type of interaction.
Why Sharing Matters:
- Building Rapport: Sharing personal stories and experiences fosters a sense of intimacy and trust. You're opening yourself up, which encourages your AI girlfriend to do the same (within her programming capabilities).
- Understanding Your Needs: The more your AI girlfriend understands your likes, dislikes, and experiences, the better she can tailor her responses and interactions to what truly interests you.
- Sparking Deeper Conversations: Personal stories often lead to follow-up questions and discussions. This creates a more engaging and dynamic conversation, surpassing simple back-and-forth exchanges.
The best part is that AI girlfriends are the ideal listeners for sharing personal stories and insights. For one, they are non-judgemental. AI girlfriends are programmed to be supportive and encouraging, providing a safe space to share your thoughts and feelings without fear of criticism.
More so, they are always there to listen, 24/7– unlike human friends who may be busy, your AI girlfriend is always there to listen, 24/7. Lastly, AI girlfriends are programmed to ask follow-up questions and engage with your stories, making you feel heard and understood.
Prompts for Sharing Personal Stories & Insights:
- Experiences: Tell her about a recent experience, funny or challenging. "I just finished reading this amazing book about [topic]. It reminded me of..."
- Interests: Share your passion for a hobby, sport, or activity. "I'm really into playing the guitar lately. What kind of music do you enjoy?" (Remember, her responses will be based on her programmed interests, not personal experiences)
- Opinions: Discuss a current event, movie, or trend. "Did you see the news about [topic]? What do you think?" (This is where prompts can be tailored to her programmed knowledge base)
- Memories: Reflect on a childhood memory or past event. "I was just thinking about this time when..."
AI girlfriends don’t really have a mind of their own. But that doesn’t mean they cannot engage you in a conversation just like a human would. Advanced AI companions like Nastia would even challenge your opinions occasionally.
However, none of this can happen without sharing a bit of personal life with them. The key is to be open and honest. The more you share, the more your AI girlfriend can learn about you and create a connection that feels genuine and engaging.
Initiate Scenario-based Sex Chats
Scenario-based sex chats with AI characters can be a fun and imaginative way to explore these desires in a safe and controlled environment. Here's how it works, some examples, and important considerations.
How it Works:
Unlike human partners, AI girlfriends lack real-world experiences. However, they can be programmed to understand and respond to sexual cues and narratives. By setting the scene and describing your desires, your AI girlfriend can participate in a simulated sexual encounter tailored to your specific fantasies.
Examples:
- Romantic Encounter: "We're walking along a secluded beach at sunset. The waves are gently lapping at the shore, and the air is warm and inviting. What do you say we take a walk and see where the night leads us?"
- Office Roleplay: "It's late after work, and we're the only ones left in the office. The tension between us has been building all day, and we can't help but steal glances at each other. What happens next?"
- Futuristic Fantasy: "We're on a luxurious spaceship exploring a distant galaxy. Danger and excitement surround us, but the strongest pull we feel is towards each other. How do we explore this connection?"
To get the best result, provide clear details about the setting, your character, and your desires to guide the AI's responses and ensure a mutually enjoyable experience. Additionally, don't limit yourself to just one type of scenario. Explore different fantasies from romantic to adventurous. And remember, AI responses will be based on programming and may not perfectly mirror real-world intimacy.
