I could just as easily have said so many I don't know but that seems more like a bad attitude than a fact. I have had more than 200 women as sexual partners and as many men (consensually) as I can count on one hand. I think the rest of you are just lazy. Anyone in their mid30s who has had less than 20 partners seems naive to me. But there are huge cultural differences between those in polyamorist or "open" communities and serial/monogamists. I wonder what role education, travel, metropolitan vs rural has?
BTW I'm being playful (honest but playful) and don't mean to offend anyone. I completely support everyone's right to craft their sexual partnerships is the model that is most desirable to the parties involved.
