Stat I've seen is 1 in 10,000. I sucked myself off from age 12 into my mid 30's, lost flexibility. Average size but could hit the back of my throat and suck my balls. When I tried cumming in my mouth, hated the taste. would bring myself right to the edge over and over, 1,000 times better than any BJ you can receive. Miss it so much.
