Trust and communication are the building blocks of a good relationship. The glue between those blocks is obviously sex. So of course, it goes without saying, that being able to talk with your partner about sex is important. A certain amount of “history” should be discussed. If there is one question or answer, however, that really makes people squirm it’s, “what’s your number”. It’s been said that with women you add five and with men you subtract five, but I think that’s bullshit. Or maybe I’ve just know a lot of easy girls. Anyway, the experts over at Dr.Ed got together and polled 1000 Americans and Europeans on the subject and the answers are pretty saucy.
