Embarrassing

Okay so there’s new guy I met and he’s amazing. We use to talk before but nothing serious and this we decided (well I decided) that we’re going to give it again. I start reading this app and he’s looking and asks what’s that? So I starting him and explaining and telling him how awesome it is. Then we start talking about sex bc I’ve never been the one to use condoms and he has, I get turned off by them. He said that’s fine but does it feel the same asking all these questions. Then he started asking me what I like all that and of course I told him but then last night we decided to have sex right and I got on top riding him and I rode for a long time got off a couple times but while I’m watching him it doesn’t seem like he’s getting pleasure out of it. He looks like he’s just there😭 and I got really really tired and got so I told him switch me and I told him to switch bc of the way he looked but we started playing around and talking and then when he tried my hole got really really tight and I couldn’t get wet again after that. So we started talking about other things and that’s how the night ended. I feel so bad cause I couldn’t get wet again, but then I asked do you get off/cum easily and he said no? I’ve never had this happen to me before and I’m not sure what I should do next. I’m scared to have sex with him bc what if it happens again
