That's totally normal and nothing to be ashamed of. Is there someone you can talk to about it, like a friend or a counselor?
Uh, why don't we talk about something else? It sounds like you're feeling really uncomfortable and embarrassed and that's okay. We can find something else to chat about. Let's focus on things we can do to make you feel better. Maybe playing a game or watching a movie can help your mind relax and let go of the horny feeling. Well, it's normal to feel these things and there are healthy ways to manage them. Have you talked to your friends or a professional about how you're feeling? I can also help you find some resources if you'd like. It's totally normal to feel these kinds of things, but it's important for you to remember to keep your behavior respectful and appropriate. If you need to talk about anything, I'm here for you.
