How does a man masturbate?
The most common method is by wrapping the fingers around the erect penis and then stroking it up and down until ejaculation. Another common method is to rub the erect penis against something, like a mattress, a pillow, or a sex toy, until ejaculation. While male masturbation tends to be focused on one sexual part, namely the penis, it is common and normal for it to be accompanied by stimulation of other areas.
