It is a fact man like prostate massage.
When I put my finger in my BF ass he goes crazy and he manages to cum a second time

My g/f knows I love it so she slips a finger in when she is blowing me. It usually makes me cum quite quickly so she usually does it at the end. The orgasms are def more intense!
I've rubbed around there and a lil poke of the finger but that's pretty much it. I have real nails. My hubs likes it and I know his finger goes there sometimes during his masterbations "when noone is looking."
