Survival of the species, jealousy locked into our dna so men don't get cuckolded and women get their dinner brought home by the caveman. But we have moved on from caveman days and all this guilt and staying faithful crap means only one thing...BOREDOM!
The one thing OP didn't really acknowledge, that I saw, was what about if the cheating housewife is seriosuly fucking over a good husband/partner/etc by doing that? Or do you side with the crowd that says as long as you aren't cheating on your partner you aren't doing anything wrong? This theory is such bull shit in my opinion - all you people that sleep with married people or people in committed relationships know that you are indirectly hurting someone in a very bad way but you lie to yourselves. My thinking is that knowing someone is cheating on someone and not telling the person getting fucked over is no different than watching a stranger beat the fuck out of another stranger and just standing there and watching. Shit... people kill themselves over affairs and infidelity - a beating seems like less to me. And if anyone's going to ask - no, I have not been cheated on ever... that I know of... but I do like to rant about it.
I agree 100% with Yazzz. People engaged, in any way, through action or inaction, in infidelity, are engaged in causing great harm, maybe future harm, to individual(s). A lot of covering of the ears and going LALALALA around here.
Good point Yazz, I think some people I know are actually on a power trip, by fucking someone else's wife, because it makes the feel like they are getting one over on someone else as well as getting some fun. Sad attitude, but I've seen it played out that way. You are right, but but I've got this dangly thing between my legs and it's like it's ruling my brain sometimes, I draw the line at rape, underage or icest, but sometimes you have to push the guilt and the common sense to one side and just have some fun with another consenting adult!
I can see that your profession would make it easier to emulate a stud and nail everything in site. Nice side line. I wonder if your wife might like to hire a plumber to take care of her plumbing. Free love implies that both parties are doing so, other wise it is stepping out. If you choose to do side jobs, do not be surprised if or when she finds out, your own house comes down around your ears.
