Hey man, nice post, I too have been wondering how other guys handle this situation, so I truly hope more will answer, theres a lot of questions and ill try to answer them all, but if I skip something or if this post inspires some new thoughts feel free to ask away.
Lets start things of with why I enjoy MLTR, basically theres two reasons for this, much like you I only rarely enjoy one nighters even though when I'm out i game specifically to get laid the same night, I however often turn my ONS into F-buddies to enjoy a more personal connection, the second reason is that though I do want a committed long term relationship somewhere in the future, I am at a point in my life were i have a hard time being faithful, and I don't like cheating, so MLTR are a good way to get both sex on a regular basis, and a bit of a connection without committing too much to the girl.
Almost all of my female friends are either MLTR, previous F-buddies or girls that I've slept with at some point, and it works very well for me, i love to have the freedom to get laid when i want to and still go sarge if thats what i feel like doing.
there are however some pitfalls I have found that generally can hinder my freedom in being with other girls, one of them is that like any form of relationship, whether friend, girlfriend or F-buddy, you have to work somewhat or the interaction will wither, this is not necessarily a bad thing, and you can use it to revert a F-buddy back into a friend if you want to cool things down for a while, however it does mean that if your F-buddy has a tendency towards using you as a bootycall when shes out drinking you can't keep turning her down because you're sarging other women because in the end that will make her stop calling you and start calling someone more reliable.
also i make it seem like the girl I'm with is always my primary choice since no one likes to be a failsafe, of course they know somewhere that it's not always the case, but the cat fight mentality many girls have, will kick in and make them feel good about themselves if you make them think that it is.
I generally travel in many social circles and thus I don't introduce the girls into my circle as much as they introduce me into theirs, personally I'm a very adaptive guy and i enjoy hanging out with a lot of different people, this also gives me the added benefit of a massive social life, with a lot of girls that are right on the edge of my social circle, and i find them extremely approachable and friendly.
another thing i like to do which generally works fantastic but can get you in a spot of trouble if you're not careful is what i call:
Ripping through the social circle
it's basically the idea that social prove transience into the bedroom, I will sleep with 3 or 4 girls in the same social circle but without any of them being best friends close, in order to establish a reputation as a sexual guy who is a great lay, and who doesn't brag about having slept with you, the girls will talk about it, so they will know, however I don't spread the news, and I find that this type of reputation will get me laid a great deal with almost no effort in that particular social circle.
Naturally I convey a lot of sexuality and therefore people usually figure out themselves that I have the women i need in my life, so guys don't find my braggy and generally neither do girls, however i do have to provide some damage control when my afc friends spill the beans about how many I've slept with, however sometime guys find me threatening which means I'll have to deal with a lot of AMOG's my general friends are as a product of that usually female and/or gay with few male friends who are either very confident or sees me as the pack leader I.e. the mans man
and yes I tell people I'm single since i am free to pursuit any kind of relationship with a girl i meet, man this was a long one, but there it is.
