How do I appreciate my boyfriend’s body without making him uncomfortable??

For context, i’m 19F and he is 19FtM. Not sure if it’s relevant, but he’s been on T for over a year/around a year i’m pretty sure.

When we have sex, he is usually the top. I know he is very much not against bottoming and i’m not against topping it’s just not something i’ve ever REALLY done.

I’ve touched his body pretty much all over, ate him out, etc. but i don’t know if that’s enough??

how do i compliment his body in a gender affirming way during sex AND outside of sex? I really do love the way he looks and i want him to know that without me accidentally making him dysphoric or anything.

Thank you for any advice!!
