The author of 'Learning Late' thought he was a late bloomer at 13, it was age 15 before I was able to shoot.
My dad never got around to 'the talk.' Fortunately, I had a friend in junior high whose grandfather was a physician. His grandfather made up for the reticence of both of our dads.
My friend (M) was able to climax a year or two before I, but he stroked dry. I, too, am circumcised, and though I tried until I was sore, I was not (then) able to stroke dry. Then one day while taking a bath, I continued washing my member, because it felt so good. I climaxed BIG TIME in the bath water.
Afterwards, I scoured the tub, fearing that my sisters might get pregnant othewise. None of us 'children' were allowed to use the shower; the stated reason being that water pressure variations might get us scalded in the shower.
Thanks to more openness today, AND to websites like Solotouch, young people today have more sources of this. essential information.
