This thread made me laugh at first, then think.
13 full sex...
Of those I can only remember 8 names. I literally had to go, that girl I met at the concert. That chick at Jim's party.
3 were Long term relationships
4 were more than once (though two were on long term booty calls... god I miss college)
Thus leaving 5 pseudo ONS, though one was a friends girl that wanted to experience a gang bang and I was on the short list, and another was a girl one of the booty calls brought over for a threesome.
I tried to figure out the blow jobs. Then I realized I would have had to really sub categorize this figure. I maybe the only guy, but I've received more than a couple blow jobs where I never got to finish, so do those even count?
