I was in an 8 year relationship. Never cheated on her once.
The relationship is over now. Am I glad I never cheated on her? Fuck no. Wish I'd fucked around with every girl that I had the chance with. At this point, what's the difference?
Shit isn't black and white. And to me, most of the things I regret doing are sexual opportunities I passed up, not the ones I took.
I have been 'the other man' in the past too. You can get all high and mighty about your morals, but that shit feels good, man. Fobidden sex is the best sex. It's like a trade-off: you endure the pain of being cheated on in exchange for the chance to be the other guy once in a while.
We're not on this planet for very long. Enjoy yourself. You don't win a special prize for being 'virtuous', so have some fun.
I'm sure some men here can agree with me on this: You can have one night of (safe) sex with a random stranger and it doesn't mean you love your woman any less. Sex is sex, and if a shot of fresh pussy keeps your head on straight, go for it. Straight up, monogamy is HARD.
I really wonder about all you 'White Knights' that are so hypersensitive about this issue. Tell us about the woman who fucked you over so hard in the past to make you so insecure and hypersensitive about this issue that you feel the need to condemn anyone who cheats, even to the point of ratting them out? Do you really think you can fix human nature with your moral policing? That if you quest against infidelity long enough you'll make all people see the light, and then you'll never have your insecure heart cheated on again.
I'm gonna quote Chris Rock here: "A man is only as faithful as his options." Really, how long would you noble crusaders be able to say 'no' for? I remember the Tiger Woods thread people were coming out of the woodwork criticising him, claiming they'd never cheat in his situation.
Bull-fucking-shit. I'll bet my life on it.
