Here’s a study that will make you blush.
Canadian scientists tested the sensitivities of several sexual areas on the female body, including the parts in the perineum area–the area between the anus and vulva–as well as the side boob and nipple. They compared these to neutral areas on the body, like the neck, forearm, abdomen.
Exactly how did they go about this? The researchers used light touch, pressure, and yes, vibration to assess how sensitive these body parts were. They had 3o healthy women between the ages of 18 and 35 get undressed and lie on a table covered in a bed sheet. They then used scientific instruments to apply the various forms of touch to the women’s clitoris, labia minora, vaginal margin, anal margin, lateral breast (side boob), areola (the small ring of skin surrounding the nipple), nipple, neck and forearm.
The researchers applied stimulation for 1.5 seconds, then waited for five seconds before asking the women if they felt it.
Here’s what they found.
For light touch, the neck, forearm, and vaginal margin are the most sensitive areas, and the areola is the least sensitive. When it comes to pressure, the clitoris and nipple are the most sensitive, and the side boob and abdomen are the least. Lastly, when it comes to vibration, the clitoris and nipple are most sensitive. The clitoris was the most sensitive to vibration out of all the body parts.
Overall, the researchers found that the genitals are more sensitive to pressure and vibration compared to light touch, which they found “interesting” because people enjoy sex and sex toys. (Duh).
In all seriousness, the researchers say that understanding these sensitives is useful knowledge for breast augmentation and gender reassignment surgery..
