With hundreds of super sensitive nerves in the nipples, it's no surprise touching or squeezing them can feel amazing especially during foreplay or sex sessions. If you want to take your nipple pleasure to the next level, consider going hands-free with a pair of nipple clamps. These, when attached to the base of the nipple, add pressure by pinching the nipple and restricting blood flow resulting in heightened sensations for the wearer.
Before applying make sure the nipples are erect then apply them to the base of the nipple near the areola. Pay attention to your body and if they are uncomfortable, adjust as necessary. You'll want to start with the lightest pressure and then work your way up. When ready to take them off simply loosen then remove. Never tug or rip them.
