This is generally not the sort of conversation I have with my residents, but Molly and I were discussing masturbation the other day. She has had several sexual partners, and in between she refrained from masturbating. Her idea was that if you know your body too well, and can easily arouse yourself and--is this the term?--come, have an orgasm, whatever, then your partner is at a disadvantage. Instead of exploring together, you just sit there and wait for the guy to get it right, and figure out what it is you enjoy. She and a mutual friend were discussing it a while ago, and I was somewhat startled to find he did not entertain himself thusly. I guess it is somewhat unnecessary, what with his fiancee and all.
