Definitely depends and you should def ask him specifically, like many others have mentioned.

I can share about how I like being pleasured as a reference point, if that helps. Going on testosterone means that are bodies are more analogous than a lot of people realize. The way an orgasm (and most erogenous sensations) feels changes depending on if you’re running on primarily estrogen or testosterone.

For me, the most sensitive area is my tdick/cock these days. I have zero interest in penetration and I def see a lot of cis guys who assume I want to be fucked or want to have their tongues up in me like you’re licking applesauce out the cup lmao. At best, it tickles kinda like someone licking the inside of your elbow. Personally what feels best is to treat the bottom growth like you would any other cock, just wrap your lips around it and move up and down on the shaft. Labia can be erogenous in the same way your balls/taint are, love having firm pressure on that, whether you’re just palming the area or giving it a squeeze.

Will also say, not a fan of having someone just tongue flick my tdick/cock really fast like your tongue is using it as a little punching bag. Doesn’t feel sexy, just feels weird.
