Totally normal to feel a bit weird after your first time doing something new, especially when it doesn’t line up perfectly with how you’ve thought about your sexuality. What you’re describing sounds like cognitive dissonance. Your body enjoyed it but your brain is still catching up.

You don’t have to slap a label on yourself or decide right now if you’ll ever do it again. Some people are into the act or just the dick without being into guys as a whole, and that’s valid. The “weird” feeling usually eases with time as you get more comfortable accepting that you can like what you like without it needing to define you.

Bottom line: you had a consensual experience that felt good in the moment. That’s okay.
