Obv you don't get my points. Obv we aren't tuned in to the same channel and can't hear each other correctly, so not sure if i even want to bother but this one point at least i will respond to ----
My point is, both people out having sex with others is either
1) bound to lead to trouble because intimacy often naturally comes with sexual activity. That intimacy involves caring, concern etc. The guy makes your woman feel awesome and she ends up spending more time with him and this makes you dump her
or
2)there is no intimacy, it's only about sex so no worries about her developing feelings for this other guy, but then its sex without feeling and according to you, theres more to it than sex.

You argue for and against both. SAying, "no there's more to sex than just sex", yet at the same time, if feelings develop (often called a form of a relationship) then you would end it.

Comes down to WHAT are you wanting outside of the marriage/relationship? Why is one woman's body not enough for you (though i realize now that you are the guy who's g/f hasnt had sex with him in 15 months or longer) if its not just the BODY of another woman you want, then its the interaction too.. right? hanging out? spending time? sharing thoughts?

What is YOUR reason for wanting to be with women outside of the relationship you are in?
What is monogamy? and if monogamy is not for you, what is the word you use to describe the opposite? Polygamy?... and THATS not just about sex that is often about caring too.. and once again, caring leads to people spending time with that other person. You might not be #1 if youre busy out with someone else and she happens to also be with someone else. and to say that if she liked another guy and sometimes wasnt home when you wanted her there, that youu'd end it with her THATS about you wanting to be in control of her polygamous relations and THAT is not true polygamy.. its about You wanting to be with whoever you want, when you want it.
Wow man, you're just like.. really frustrating to deal with.
