I'm very much about low effort relationships; its one reason I love tinder. Im really busy with school, work, and the gym so I really don't like spending time meeting girls for dates that don't go anywhere. This is why I started bringing up that I am just looking for casual sex or ongoing friends with benefits right upfront when talking to girls on apps like tinder. I have a few girls now at my university that I have made this "arrangement" with where we just basically went right from tinder, to sexting, to friends with benefits.

I kinda want to streamline this to the point of just putting them all in a group chat of sorts and just hitting it up to see who's free when Im looking for sex, as opposed to going one by one. Ik that alone isn't gonna save much time but I was also thinking that I wouldn't care if other guys joined so long as it meant they brought more girls to the group, and this would just mean a better variety for everyone. I have a good friend who is in the exact same situation (even same busy major, and spends same amount of time in gym) as me but he just has one girl that he fucks instead of multiple, and he only sees her as easy sex. I've told him he could easily set this up with more girls but he doesn't seem too interested. He would be the first guy I'd consider adding because I know he could easily bring in more girls, and is just as detached emotionally from the sex.

Another benefit I thought of is that I would feel less weird asking girls about being STD tested if it was for "joining a group" as opposed to "being one of my fuckbuddies".

Any advice on pulling this off? Is it just a bad idea?
