The researchers recruited around 30 women between 18 and 35 years old and asked them to lie on a table covered by just a bed sheet. They were also asked to wear goggles in order to blindfold them during testing. The researchers then tested the sensitivity of different body parts with the help of scientific instruments by applying stimulation for 1.5 seconds and then waiting for 5 seconds before asking the women whether they had felt it.
The researchers found that neck, forearms and vaginal margin are the most sensitive to light touch and the clitoris and nipples are most sensitive to both pressure and vibration. The study has been published in the Journal of Sexual Medicine.
"This study focused particularly on younger women to establish a first series of normative data for light touch, pressure, and vibration sensitivity on the perineum and breast area. Few studies explored multiple sensory detection thresholds on the perineum and breast, but these normative data may provide standards for clinical conditions such as aging, genital and breast surgeries, pathological conditions affecting the genitals, and sexual function", the researchers wrote in their report.
