What can I do to enjoy gay sex?

Hi guys,Well, I'm 100% gay, for sure! But here is my problem, I never really had gay sex before until like a couple weeks ago when I finnaly did it with a boy from my college.We bj each other, but I never really felt any pleasure while receiving it. I also bottomed for him, but despite of being painful, I couldn't even sustain a hardon.Yesterday I went to a gay sauna here in São Paulo and topped for a pretty nice guy. He did blow me, and it did feel good... Anal sex was good too, but I didn't cum...When I masturbate, I can cum just fine... sometimes very quickly... Last night I spend like an hour fucking the boy, and didn't even come close...Does anybody feel like that? Please help! :Dthx
