Is this a good way to choose who to date?

[Lovely]

Having sex with both of them and using that as the deal breaker is not a good or smart idea. You're not going to be dating their penis. Sex is fleeting....It is NOT a good foundation for a relationship, so don't base your decision on that. A good foundation for a relationship is respect, honesty, FRIENDSHIP, loyalty, and communication. Sex is what comes after, like after you're married when you're with the one you're supposed to be with.
To be honest, I'd advise you not to go for either of the guys. If you can't make a decision, then neither of them must be the one. I think that when you meet the one, you just know. It's not a love-at-first-sight kind of thing, it's more of just an instinctual decision.....It's hard to explain, but I've experienced it. There have been plenty of guys, great guys, whom I've liked and whom have liked me, but for whatever reason, none of them compared to the guy that I'm with now. He just has that extra special something that I can't quite put my finger on.
