Define "dating."
Some people have deep emotional scarring that prevents them from even contemplating such a hedonistic, heinous act.
I, on the other hand, have almost no morals when it comes to the fairer sex. Bad sex is better than a good day at work.
In my heyday, I once juggled three women for about two months straight. Great way to lose 20 pounds, go broke, get dehydrated and get almost no sleep. But man, was that fun.
Oh sorry...this is about you, right?
It all depends on you, buddy. Obviously, you're not telling Girl A that there was a Girl B in your bed last night and same goes for Girl B. How would you feel if one found out and started bawling her eyes out? Would that bother you?
Also, how would you feel if that same girl slashed all four of your tires? These are things you must contemplate.
