Pocket right above the base of my cock

So, my wife and I were fooling around and she starts riding me. Nothing different so far. Then she’s grinding hard and harder and I feel her pussy grip the base of my cock and pull down, let go, pull down, let go. As she’s doing that harder and harder, I suddenly feel this pocket form below my pelvic bone (pubic symphysis), right above the base of my shaft:

I could feel my wife’s clit grinding into the pocket, then grinding out right onto the pelvic bone itself. We discussed this later and she said when her clit was in the pocket, she could feel the pelvic bone way too high. She had to get her clit out of the pocket to rub it properly.

Has anyone else here felt this pocket?

ironaddict has the pocket clearly visible in his pictures on his thread in the pictures forum.

I also have the pocket. It became visible after a month-long period of swinging weights, when the exit point of my penis lowered from it’s original position.

That’s it!!

Ok, it probably is the exit point getting lower. This makes sense as I really can’t feel much of it any other time.

Apparently you have never been kicked in the balls and couldn’t find them. There are pockets up in there so they can disappear, yeah, it doesn’t feel all that great. I guess is built for cold weather so they keep warm and hide up there from time to time.
