One word.
***Never***
I couldn't ever hurt Synthetik and do that. It's not even something I am mentally or physically capable of considering. Every single fiber of my being would not allow it to even begin to happen, that is just how I'm wired. I think I mentioned in a thread a while back about how I cannot love, lust, make out with, kiss, be intimate with (and etc) anyone other than the person I love and have feelings for. Synthetik is the only one, and will always be the only one. I'm with him, I don't even take notice of other men's attractiveness, at all, no matter whom they are.
I am completely, 100% monogamous, and fiercely so. When I say that, I literally mean it: I need no one else other than him.
(Please note: That up there is not a 'dis' to anyone in poly or swinger relationships *at all*. I may be monogamous, but I respect other's relationship differences completely I'm sorry if I seem rather stern on this issue, as someone who was cheated on in a past relationship, I know firsthand the hurt that one feels from it. Even if the guy was just a High school boyfriend, and not, say, a husband of x number of years; it still hurt me very badly nonetheless)
