I was straight for 23 years, but now I'm experimenting with a guy next weekend and I'm super nervous.

After I started giving myself prostate stimulation, I started really opening up to the idea of having a gay experience a lot more. I found a guy on an anonymous hookup app to do it with, and he's very down (and I set our terms, no penetration sex just yet only oral sex) but I'm still extremely nervous. Excited nervous too, but nervous like I might get cold feet.There's like a million thoughts running through my head, what if I don't like it, what if I like it more than straight sex, what if someone I know finds out, what if I'm bad at giving head, what if, what if.Anyone have any advice for me or why I might be so nervous about this? I would love to hear thoughts from anyone who's been in my position too.
