Bad Orgasm With Cock in my Ass

[trubl]

I have struggled with having a satisfactory orgasm while I'm being fucked by a partner. If I'm being fucked and have a cock in my when I ejaculate I get all the feelings of impeding orgasm, it is always way more intense with a cock in my ass right up until the moment that I start to spurt and then its like the pleasure is suddenly muted. I'm wondering if anyone has experience with this phenomenon and can help me learn to have a better orgasm. It isn't always the case tho, sometimes there is an explosive orgasm with ejaculation but I can't seem to put my finger on what different is happening when I fully enjoy the experience. Thanks
