Uterine oragsm from navel licking
I am 20 and since my childhood, I have a belly button fetish. To me the most arousing thing would be to have my navel licked, especially by another woman. I have had that experience in the past, more than once. And I came every time. But on a few rare occasions, during my orgasm, I had this feeling like something was convulsing deep inside my belly. It was a little painful, but it felt sooo good! Is this normal or is it even possible that I had an uterine orgasm just by having my belly button licked?
