I am interested to have some exchanges with others who enjoy nipple play. Are there many of you that use clamps, clips, or rings to excite your nipples? Having my nipples pinched during sex has become increasingly pleasurable as my nipples become more sensitive. I believe the increase in sensitivity is a result of frequent clamping and pinching I now receive. Are others experimenting with this "kink" or are very few interested? I would really like to get some ideas and suggestions on what others are doing.
