I owe Andrew a taint post.
You’re all aware, I hope, that if it’s a part of your own body, you’re allowed to touch it in any way you want. This is a part that you can’t see unless you use a mirror, so you may have neglected it.
The perineum. It’s a smooth patch of sensitive skin between, in women, the vaginal opening and the anus or, in men, between the scrotum and the anus. You hear it referred to as the the “taint” because, like, “‘taint pussy, ‘taint ass.”
It’s VERY VERY VERY VERY SENSITIVE. Therefore early in the arousal process light touch is the way to go. Soft, gentle, preferably lubricated touch with fingertips. Later in arousal, pressure can be good, but it takes quite a high level of arousal to make intense pressure feel nice. Light touch is pretty much universally nice.
More than anything, stimulation of the perineum is a superb addition other sensations. Added to your standard masturbation routine (or to oral and manual sex on your partner), it can amplify other sensations.
Try it out. Totally good.
