My experience with edge-play is very different than what I've read here. I'm referring to tease and denial. That's when a Domme, while I'm tied down, teases me to the point of cumming, then stops. That's very affective, because in that state I'd do anything she wanted. I've had that happen to me. In fact one Domme took me up to the point of exploding five times, but each She'd whip me until I lost the hard-on. Then She'd send me back up again. Finally, the last time I was up, She flicked the head of my cock with Her finger and cum dribbled out in buckets.
