It sounds like you have some issues to work though that are beyond my experience. I'm going to address a few things that stood out to me in your response as best as I can.
No cuddling. No connection. No conversating. Just sex and dipset…
They need genuine conmection physically , sometimes even psychologivally, wtih anither person sometimes for hours and hours.
A FWB situation does not preclude cuddling. I've sometimes spent hours doing so. Even without actually having sex at all. The main difference between that and a full relationship in my mind is that you're not each other's "person", there's no obligation to each other beyond what a friendship entails, and you're open to get involved with other people should either of you want to. There's still a genuine connection there and you should care about each other as you would anyone else you're friends with. You just have to communicate and make sure you're both on the same page about it.
Also that hanging out at events thing
is questionable as a methid to find people to treat touch starvation with
That isn't how I would approach this. You're not making friends to deal with touch starvation, you're making friends to have friends. You find cool people who you like hanging out with regardless of any kind of sexual entanglement. Occasionally something else grows out of that but if you're going into with ulterior motives you're unlikely to find success. I've known these women for a long time before anything sexual happened and I wasn't looking for it when it did. I think the reason they were comfortable with me is because I've always been open about my stance on relationships and I've never tried anything with them or anyone else in our group so they felt safe with me. When something did happen I paused it to set clear expectations about what we did or didn't want out of the situation to ensure no one would have any regrets. So far things have worked out. We don't hook up every time we see each other but it's nice when it does happen.
There are a notable number of people out there at these events whjo will befriend you but will think that youre ‘too weird’ or ‘being too much of a creep’ or ‘being too much of a softie’ if you ask them to help you with your touch starvatiom just as you will help tjem with theirs
That's because that is extremely creepy. If you're after touch/sex from the start you're probably better off just dating and making that clear.
But Ive come to realize that meeting friends at events is surprisingly the only consistent way that a lonely childfree adult can meet ANY friends or ANY partners to meet long term
Yes, the best way to meet people is to go out and meet people. Not everyone is going to click with you but it's important to try and when you find someone put the effort in to build on those connections. It isn't going to all come at once. It takes a lot of energy but in the end it's worth it.
