According to "Urban directory"
Edging
Top Definition.
Coming nearly close to climax or ejaculation,then purposefully stopping sexual stimulation in order to delay the same, so that the ultimate climax will be more intense. Unlike the other two definitions of "edging" so far included in this dictionary, it is not a practice necessary inclusive of masturbation ("wanking"), but is also practiced amongst homosexual (and, I suppose, heterosexual) partners/couples.
"As we were edging,every time I got close to cumming, I'd withdraw and wait until immediate passion passed, and he would do the same, until neither of us could tolerate it any longer, and we both shot our loads: mine in his mouth, and his on my abdomen.
2.
edging
When wanking. The continual bringing to the edge of shooting a load but backing off to prolong the pleasure.
I’ve been wanking for hours and edging, man my balls ache real bad.
3.
edging
approaching the edge of sexual orgasm and withdrawing, usually several times, before finally achieving orgasm. meant to intensify orgasm, and for men, volume of ejaculate and force of ejaculation.
this applies to any sexual act and is not limited to masturbation.
My girlfriend and I like to edge before we fuck. She performs oral sex until I'm just about to cum and then we stop for a minute, preventing orgasm, and then we have intercourse. After edging like this our intercourse lasts longer and the orgasm in stronger.
