12 (insert Dirty Dozen joke here). Mostly they've been girlfriends, a couple were one night stands between girlfriends.
Also, to those in their late teens (or even older) who think they're "forever alone" - I was 19 when I lost my virginity (I'm 33 now). I spent the next 7 years with the same girl, 2 years with another and just over 1 year with a third. The other 9 were a mix of short-lived romances (7) with a couple of one night stands in between, but all clocked up in more recent years. In other words, it wasn't until I was in my late 20's and early 30's that I flourished in that department. Don't sweat it, there's someone for everyone.
