As long as I can remember, when ever I have been sexually aroused I have feelings inside my butt, even through puberty when I would wake with a erection I would feel some tingling and a wet feeling from my anus, because I shared a bedroom with my brother, I would go into the bathroom and sit on the pot, then with one finger I would rub my anus, it would feel swollen and slightly dilated, taking some paper I would rub and probe my hole and wait for a slippy wet feeling, I would then examine the paper, generally it would have a slightly brown jelly like substance, some times this would be clear, I would then take a clean piece of paper and rub the outside of my hole, within a few strokes my legs would want to clench together, then moment's after my feet would curl and my knees would shake and I had a dizzy feeling heart pumping, lip biting I now know as a anal orgasm.Now I can cum in any position, but strangely the best experiences are with either very effeminate men TS, trans, cross dressers, or very very dominate females
I still produce sometimes in vast amount's when clean a clear jelly like substance, which smells and taste`s very good, and I do not need a lubricant
and yes I have been checked for STD`s and cancer, and colon abnormalities and all is well
guess I am just a lucky guy
