text: MDMA or "ecstasy" originally gained popularity in the 1980s among college students. According to a survey conducted, 10% of college students at a big US institution reported using MDMA, with alcohol and marijuana being the most often used substances. MDMA users report increased enjoyment in physical contact and proximity rather than a sexual experience. MDMA has been shown to impair sexual performance, including erectile dysfunction and delayed orgasm, as well as to suppress sex desire.
