i (22f) have never been able to cum during sex

I feel a lot of shame about this. I think it makes my sex drive even worse because I'm never fully satisfied and still want more, but whoever I'm with always gets to cum and then can't do anymore. I'm understanding because I know it takes a while, I just wish they would try a little bit harder/longer to make me feel good too. I do a lot for the other person and I enjoy it, but I always feel like I need more. I don't like having to ask, I wish someone would just want to do it for me like I do for them. With men especially it seems they get offended/butthurt easily that I can't cum, but they hardly even try. So i'm afraid to ask for that reason as well. I don't want to seem pushy but my needs aren't being met. BY THE WAY I can make myself orgasm in about 5 minutes if i'm by myself. Honestly it could also have to do with how much I've masturbated in the past. Maybe I can only orgasm if I touch myself? I don't understand. I thought men wanted "freaky" gfs. I'm very upfront about my high sex drive. They all say they can handle it... It makes me feel so dirty to have to ask for more touch or head or whatever so I just try to forget about it. It's like physically painful trying to suppress my urges. Am I just going to have to accept that I will never be satisfied by sex with a man? I'm even more afraid to be rejected by a woman :-(
