The use of a Nipple and or Clit Clamps can definitely enhance any sexual act. Clamps are usually used by women who are into the excitement of feeling pain. Some will also find them to be very submissive which will bring both punishment and discipline into the sex play.
What actually happens to your nipple or clit, when you use a clamp? First you feel pain and as it cuts of the blood supply to the area, it will become somewhat numb and the pain will subside. When the Nipple Clamp or Clit Clamp or both are removed, and the blood supply is restored, some pain sensation will reoccur.
When the increased blood flow enters the Nipple or clit area, it will intense the sense of touch significantly and make your sex act more enjoyable. Clamps should not be left on for more than 20-30 minutes, but there are some women who enjoy them for a longer period of time.
Remember though, that Nipple and Clit Clamps do cut off the blood supply to the area and the tissue will eventually die, if they are worn for a longer period of time. Also to be mentioned, using Clit and or Nipple Clamps are not tools to ensure an orgasm by themselves, by any means, but they will definitely intensify a climax once you reach it.
