Sex with others while your married, can be wrong, unless you have an open relationship, and both parties are clear about this. But thats not what this is about, you can pass aids on to your wife and or husband without ever cheating on them. So, the point is moot. And sex isn't the only way aids is transfered, it could be transfered by an open wound.
And no apologies necessary.
I know that but as I said that is what got it revved up.
