well, having had a one night stand when I was single is one action that I would never again repeat. i never felt so dirty and ashamed even though the sex was good.

my concern is that if you did have sex with your girlfriend's husband may create a situation where once is not enough making you crave additional couplings. i can't imagine that you'd be satified with a 1 time get together.

then of course, you must consider your girlfriend's feelings and her reaction should she find out. would sleeping with her husband be worth losing her friendship.

as far as your relationship with your husband. sounds like you need some much needed communication with him and counseling. if you no longer love him whatsoever, why stay married? i think that you need to dig deep in your heart to figure out if you still love him. even so, counseling may rekindle some long lost flames.

overall, resist your urges to sleep with your girlfriend's husband. once you do, there is no turning back. maybe you could enjoy sex with your husband while fantasizing about the other man. just a suggestion. others may disagree, but fantasizing about another person while having sex with your spouse is perfectly healthy and normal.

i hope this helps. i just hate to see you bite off more than you can chew, so to speak.
