Find His Pleasure Zones Here's a little trick you can do while giving a blowjob to determine where your partner's pleasure zones are. Point his erect penis upward, cup the scrotum in one hand, then gently and slowly lick the underside of the penis from the base towards the tip. Suck along the underbelly and find the areas that bring him the most pleasure. Once you know his pleasure zones, you can really focus your attention.
