Depends on the definition of an ex. I had a lot of 1 nighters, some that became 2 or 3 week engagements, a couple 2 - 6 month long entanglements, most of them also became fuckbuddies, if we were together and horny then we took care of that. Nothing really serious until I met my wife and that's lasted 26 years, 5 months, 18 days thus far. BTW she knows about my past as well.
