uncircumsized first time attempt at sex?

last night me and my boyfriend (yes, im gay) were getting all frisky in bed, im still a virgin and even though he's gone down on me a few times, he's never fully pulled back my skin on my penis. last night he tried sticking my penis, well, ya know. and it went in a bit, but we had no condom (i wanted to wait) now when this happened he seemed to have pulled my foreskin all the way back, and now it's stuck like it. so my head is out. the foreskin isnt covering it no more. and when he tries to pull it forward the way it was before (over my head) it just rolls back, i was kinda worried at first...but i want your guys opinion, is this normal? is my foreskin supposed to stay back? my head's all exposed now and my skins rolled back. answers would be appreciated.
