I'd say cheating is cheating.
If she just wanted to have a little safe fun with someone else it probably wouldn't be a huge deal.
I guess when you get down to it, yeah, cheating is cheating...
I knew a chica i used to work with, her man was fat slob who worked in a Sub shop (he could eat all day!), She went to a strip club, and I asked her during lunch, what she thought and did she prefer their physiques over slob boy, she said the predicable, "Oh no, I love my man's body, and i didn't find the attractive at all." When i stopped working at that place, every time i came back to visit, she would always be "throwing it" at me. Yet, she was engaged (the rock was pathetic)....
I think attractive dudes are fun for many women, but due to their own self esteem issues, they know that that man is willing to stray....
Now if we can get more women to comment on this matter....
