I have been the other guy for this girl for a out three years now. Trying to keep it short, I will just say I LOVE the sex. I have never met someone so inline with my kinks. We are rather extreme in our sex with the only rule being no marks ( and it has been.broken a few times when we get to crazy). The crazy sex is actually what brought us together. Her husband says he respects her to much to do those things, so she goes elsewhere for it.

My problem is that since we started fucking I have not been able to enjoy another girl. I keep comparing the sex with this girl. Now, if she was single I'd probably date her but she is married with 4 kids and honestly I am not taking that responsibility. I have no kids of my own. So I try to find a girl for me but non measure up to her sex. I honestly have no idea what I can do. I certainly don't want to call it off because of this, but at the same time I am getting very close to 40 without kids, never married and no girl measures up.

I know it's a mess, and this subreddit is more about the adulterer but I don't know where else to go.

TL;DR Awesome sex with married women, makes finding a S\O exceedingly difficult.
