I know women who have had hundreds, sometimes thousands of partners by thirty I guess this thread is dead by now, but are you serious? Assuming they started at 15, that's more than 100 different partners a year, every year, for 15 years. Were your acquaintances porn stars or hookers? And did their husbands know they were #2001? Did they care?
This thread isn't as dead as you think because there is a nasty little secret about multiple partners for women. It contributes to sterility. Many women with mulitple partners become sterile becasue of silent pelvic inflamnatory disease.
