I don’t cum with him! Why not?

Trinity

I feel so good with him, sex is great. The thing is, before him, I had never had sex, only masturbated. When I masturbate I can cum pretty well, but when I have sex with him, I can’t, even though it sometimes feels even better! I organs a lot, but the only times I’ve ever cum have been when he gives me head. We communicate very well and he knows that I enjoy oral more, so he does it a lot, but I still don’t cum that often.

I feel like I’m doing something wrong. Especially because I could be extremely turned on and still not be very wet, and I don’t orgasm from penetration alone. I know this is common but I still feel bad when I only organs from oral and we can’t have sex comfortably without lube.

Logically I know nothing is wrong with me, but I just don’t know why I won't cum. :(
