i myself have been exploring anal sex on myself for many years . i have a penis like dildo that is thick and has veins on it . i just love the feel on my entrance going in and out . i have found my prostate by accident ,one day i was using my didlo . i was in a doggie position and was really giving my ass a workout when all of a sudden my penis felt like it explode and my groin mussles were shaking and my anus was contracting and i shot a huge load and had the most powerful orgasm of my life including femal partners. i was so euforic . my penis throbed and my anus pushed my toy out and i fell asleep right there on the floor . i awoke and tryed to do it again . i came again but this time it was just my prostate and contracting anal opening . i still enjoy having my ass full and my penis dripping to the most amazing orgasms . on a good day i can have multipul anal orgasms then jack off and have a penal orgasm . i am glad to find some one else who can relate. thanks
