Urban word of the day (a couple weeks ago): Stroker Guilt. This begins in puberty when we're told emphatically and repeatedly that jacking off is wrong, dirty, disgusting, and sinful; the worst thing we can do to a young guy just discovering the pleasurable sensations of his body.
It's why young men are so ashamed of their bodies, so shy in a locker room or gym shower.
They've been pummeled with the idea that the normal functioning of their cock is horrible.
Then, of course, they mature and marry and a new badgering begins: When are you going to give us grandchildren? Because now - all of a sudden - the things hanging from the abdomen are good.
And the normal functioning is something to be proud of.
And to celebrate.
Learning about your body and its response to all manner of stimulation is a good thing. If you have the opportunity to mentor, be open and honest. Take the time to teach them that boners are good;
that not getting them is cause for concern.
That touching and caressing themselves is normal, and one of the most natural things in life.
