Women release oxytocin from sexual intercourse, which makes it very tricky to be able to maintain a roster without hurting any feelings or having accusations thrown at you.
Hinge and clubs are going to be your main ways of actually getting these girls, bonus points for clubs if you get with the girl that night.
Hinge:
What you're going to do is start a bunch of "talking stages" from hinge which are usually an important part or the intial part of starting a "relationship", don't be cold and be extremely talkative and reply quick showing great interest, you want to go on a first date but typically don't make any moves maybe a kiss at most but I wouldn't say its worth it, now make the second date always something risky, like going to the club or going to each others house, if its the house option let it be a cute activity like baking cookies etc, however before they come around the second time they need to be completely aware that you either don't want a relationship or are "unsure" about having one, but after the first date express just how interested you are in them. If you're decently attractive you'll have some sort of intercourse if you go to the club together or go to each others house, if that doesn't happen then its genuinely over but I've never had this fail so I'd say odds are quite low.
Clubs:
This is extremely easy aslong as you're decently attractive, I've almost never approached a girl in the club but I always tended to leave with one. You either go the full way on the first night when meeting each other or at the very minimum make out, after this it's extremely easy to maintain as you've already had the intimacy, and there's little to no chance of it stopping afterwards, start going to clubs together and doing stupid other shit like hanging out and going on walks, she'll either think you guys are friends with benefits or that you're building towards a relationship.
Important note: ALWAYS make it clear that you're not wanting a relationship, I don't mean to remind them because that'll just turn them off, but always make sure they know before you have any sort of intercourse, unless you guys were both drunk at the club. You're genuinely a scum bag if you don't tell them and it won't work long term whatsoever unless they're ugly.
