What is your dividing line between sex and non-sex?
Ratio of present people and current location to Testosterone . . . .
"Dividing line"??? If you mean why would I have sex with someone vs. Not having sex with them. Well .. I'm married so that means I only want to have sex with my husband ... Pretty simple actually. I'm so glad I don't have to do the dating scene anymore ...
Ummmmmm how many glasses of wine I've had with dinner or if wine was my dinner .... :p
sex is when you do it and non sex is when you don't have sex.
Are you talking about Bill-Clinton-esq terms: "I did not have sex with that woman" (because a BJ is not "sex")?
LOL
