Not recently, but I've dealt with that a lot in the past.
To deal with it I'd just tell myself that it's my sex drive and that I just need to wait it out and my attraction will calm down. It's infatuation and don't do anything in the heat of the moment that would ruin my relationship and I would regret later.

Not tempted, exactly, but I have this weird thing where whenever I'm in a relationship with someone, every single sex dream I had is about anyone other than them. Sometimes real people, even if they aren't people I actually like. And in almost every dream, I know I'm cheating and I don't care. It's a little worrying...

Yes, guys seem to know when my hubby is out of town and start trying to "talk" to me

I haven't been tempted, but there have been other ladies that I've seen that I've wondered what it would be like to sleep with them.

My girlfriend and I have both felt this way before during our relationship and we have agreed that as long as we don't act upon it, it's okay. It's actually a pretty nice understanding. She has told me it is okay for me to flirt with other girls as long as I don't kiss, touch, and I am with her at the end of the day. I feel the same way about her. We're both natural flirts, anyway, so it's hard to keep that corked :p
