Questions from a gay virgin

So I am ready to have sex with the guy I am dating, but I'm pretty scared. A) idk why but I've never gotten off on a hand job or blow job- it feels nice, but what gets me off is just pressure, like even dry humping. Is that totally bizarre? I'm so scared that I'll finally have sex for the first time, and it won't feel right and I'll have to fake an orgasm :/B) I am really scared to bottom. I've never had anything (like, anything, ever) up my ass. so I'm as tight as possible. I'm scared of disappointing my bf or just ending up in a lot of pain.Just looking for advice/feedback/anything. thanks.
