mutual masturbation

I'm worried that partnered sex won't be as good as masturbation!

I have a question about the way I masturbate: it feels best when I am rubbing myself light and fast through a layer of clothing, like underwear or something, and tightening my inside muscles at the same time. I can orgasm easily like this, and have multiple orgasms if I keep going....

I'm coming, I'm coming, I'm......not.

asks:
Basically, my problem is that I cannot seem to cum during oral sex or intercourse. If she uses her hand then I reach orgasm within an acceptable space of time. However, when having sex or receiving oral sex, the feelings build up but never quite reach the point of orgasm. Is this normal? Is there anything I can do?...
