One up on buddies-infidelity

Anyone ever tempted to have sex or actually do it with a friend or acquiantance's wife/girlfriend just to show her how much you've got compared to her husband/boyfriend? Did their relationship last? If so, any damage to it at all?

No, that would be cheating, and I don't believe in cheating, even if she was willing or the instigator.

i'm rarely "tempted" to do anything - i either do it, or i don't

I thought it was a code of honour never to have sex with your friend's partner?

I presume it would ruin the relationship for starters.

Just a guess...

This question seems to assume that men with large penises have different sexual behavior than ones who don't. Surprise, many scandalous sluts have small weenies (or average ones). Nailing your friend's lady is just wrong.

well, if you and/or the girl actually TOLD what happened, then i figure there would be some "damage" done.

unless your friend said, " i'd like you to start having sex with my wife/girlfriend sometime... " i take it there be some "damage" done to that relationship, too.

Never...and I'm no angel, but having sex with a friend's wife or girlfriend (or sister) is a line I just won't cross. There are too many other women out here.

It just sounds like a bad idea.

Bros before hoes they always say....Friends don't sleep with other friends women/men.

I agree with what has been previously said by numerous people. Furthermore, I find the idea that someone would deliberately try and sleep with another's g/f or wife for the sole purpose of showing her that you have a superior endowment to that of her current husband or b/f petty and somewhat disturbing. There is nothing wrong with being proud of what God gave you, but engaging in that type of behaviour is definitely crossing a line.

Definitely not; that seems like a terrible thing to do to a friend. If I like the girl and dislike her boyfriend, that's a different story. If I think the guy is just bad for her and I were interested I might try to steal her away - almost did once, but there were complications on my end and I let it alone.

hummm I can hear the stinging rebukes now.....buttttt....from a different point of view.....there are some men and married couples that find it very exciting for the wife to be seduced by a bigger hung man (cuckolds and dom wife types).....the husband actually gets off on knowing it happened and being humiliated by the "superior" man etc......that isn't my situation mind you.....my hubbie knows I am an admirer of men of size.....but that's as far as we have gone.....from a fantasy point of view i think the question sounds hot......a huge guy banging a wife of GF...but most of you are right in the light of day the reality is it sounds like a good way to loose the friend and the girl.
