I only realized that I regularly masturbated several years later, when my friend described her orgasms to me. I experienced the exact same sensation! When I crossed my legs, squeezing my genitals between my thighs, increased blood flow rushed to my vulva, creating a tingly feeling. People often masturbate when they are aroused, which results in increased blood flow to the genitals. Societal messaging told me that masturbation was wrong and dirty, so how could the pleasurable experience I was having be masturbation?
