@3x7r3m157 This is the correct answer.

Guys pussy out and give commitment, because they are afraid of losing a particular girl, and then they want to bang other girls because: there are other girls, but are afraid of losing the girl they committed to. That reeks of "testicular fortitude deficit". The proper thing to do is to keep the OLTR relationship "OPEN" on your side and then bang your side chicks at your leisure.

So you either have to OLTR up a woman who is bi and down to share girls, as @itiswr1tten has done, or OLTR a girl who will tolerate your indiscretions, even if she knows she is lying to herself (ex. my OLTR and I have an "understanding" which is that she understands that she isn't going to "understand" that I fuck other girls. My slave girl knows she's the side chick but isn't ever going to ultimatum me because she's afraid of losing access to me - so she's the 'beta' in this case - and when other girls ask for exclusivity I say, "Sure, except for girls we share." which puts them on notice that the answer is "No, unless you are down for Girl-Girl-Vasya 3ways".)

@cantkillfaith probably has to lose the current girl to (a) learn this and (b) set it up going forward, unless she is secretly bi, in which case it might work. Otherwise, it's time to nut-up or shut up.
