My husband and I have a great sex life that I love. He gets me off consistently with his fingers on my clit, and my orgasms are body-shattering and euphoric. However, ever since I first had sex, I've always been a little surprised and disappointed by how little sensation I feel in my vaginal canal. I can feel a penis, fingers, and toys go in, but once they're in, it's sort of a vague sensation of fullness, and nice, but not much.
With my (and my partner's) current living situation, the only time I'm able to engage with erotica/masturbate/be intimate with my partner is quite late at night. I usually end up going to bed shortly after. Now, whenever I engage in intimacy, or even so much as daydream about it, I get suddenly very sleepy. While it's a not-so-neat party trick to fall asleep quickly, it also means I struggle with staying engaged and having energy during sex. As soon as I get turned on, I just feel so... cozy.
