Many areas of the body should not be bitten, but can definitely be grazed (like the vulva or shaft of the penis).
"Unless you break the skin, biting is a pretty low risk activity," Dr Powell said. "Those with weakened immune systems may want to have their partners shower or clean the area before biting. Until you know how prone your skin is to bruising or breaking, you will want to start at fairly low intensity levels. As with all forms of impact/pain play, warming up the area with lighter sensations will help to reduce bruising and welts."
Of course, you should also note that biting can leave marks. Combining suction with teeth can create a hickey or bruise over time. Make sure your partner is aware of this and that you choose areas that won't be immediately visible to others and can easily be covered up.
How to Deliver That Bite
Start any bite gently, then press down harder with consent from your partner. Communication, like all things related to sex and relationships, is at the center of this moment. Make sure you don't break skin, that the bites are quick, and that you don't pull too hard at the skin. Easing into the moment and the intensity of the bite is a great way to build up tension in the bedroom.
"As with most things, it's helpful to check with your partner about where they like to be bitten and how they like to be bitten before diving in. If they don't know, experiment with different spots intensities, and bite techniques," Dr. Powell said.
Psychologist and sexologist Havelock Ellis wrote that the "impulse to bite is also a part of the tactile element which lies at the origin of kissing."
But the act of biting takes things further. It's incredibly primal, savage even, and can make the emotional connection during sex pleasurable and intense. There is nothing sweeter than sinking your teeth into your lover in order to satisfy your insatiable hunger.
