My boyfriend recently "helped me find religion," as he so cutely puts it. He hit a spot he's never hit before (he's not exceptionally long, but quite thick, so only certain positions allow him to hit super deep) and it felt so good I moaned out an "Oh, god..." in between all the other embarrassing moans, groans and occasional screams I give during sex.
Contrarily, he's usually quiet during sex. Sometimes his orgasm will bring the sounds I like, usually a few sweet, slightly high gasping moans, and it happens more if we do something to stimulate his prostate. We also practice pegging, and when he's really worked up he'll give me a really cute, "F..fuck me?" And when I slip his favorite toy inside him he moans nice and low or even give me an "Oh, god," or some affirmative like, "Oh yeah...."
