How many girls have i slept with?

Well, i'm in my late 30's and i've never been married. So I've been in the dating pool for maybe 24 years or so.

I once counted how many "girlfriends" i have had. The number was in the 70's.
I have never kept track of all the girls that i've slept with but i'd say its probably double that?

longest relationship? maybe 2 years. My eyes wander so.....
