So you are asking should you continue having sex with your sex buddy. Yeah sure, if it "does it" for ya then by all means stick with what you know. I mean if the idea that he cheated on you is less than the great sex, and if the notion of trust and building a relationship of commitment comes second to sex, then you have a perfect relationship and should not give it up. Sex ain't everything and you can take a hand in your own personal pleasure - if you know what I mean. I find that sexual issues (bad sex) in relationships have much more to do with miscommunication (or total lack of communication) than what type or kind of sex people are having. If you want great sex with anyone, then you Both need to sit down and have a heart to heart about what buttons you like to have pushed in your fun parts and in what order to get you too have great sex. If you can't do that with anyone else - then you are screwed - badly. Oh, and obviously the sex isn't THAT great - because dude went somewhere else to have sex. That's a HUGE clue as to how he feels about sex with you... meaning your most likely not "doing it" for him - or if you prefer he will say down the road that you provided crappy sex.

It's NOT exclusive anymore, it won't be the same any more, you decide.:)

So, all you care about is having good sex? It sounds like he's the same way. Maybe you two are a match made in heaven! Hopefully no children result from this as long as you both have this attitude.

If he has cheated on you and sex has been so great yet you're not too concern about getting HIV or STD, are you?...

Why should you give up a good thing. Keep at it until there are reasons to stop -- like he gets a new GF, or you find a new BF. Why not?

A guy can be trained to be a better sex partner... but once a cheater, always a cheater.
