@Lavender79 - OLD is a minefield, and very hard work, particularly in the situation we find ourselves in with Covid.
I'm on pretty much all of the OLD websites, but don't have much luck (which I put down to my age and looks), but I keep plugging away.
I have met and dated some nice people, and even managed to find a FWB last year, but this year has been impossible.
I'd say get registered on more sites, and put yourself out there - it only takes one match...
@Namechangeforthis123456 - you are far too young to give up on sex! I'm 58, and I haven't!
I was very lucky last year to find a woman that wanted a sexual relationship without any / many strings. We were very much friends that had sex. We talked a lot, shared intimate details about our lives, often just watched TV cuddled up, as well as having great sex, so it is possible, but admittedly, very hard to find. (We're still friends)
If it's casual sex that particularly interests you, then you might want to consider more, er, adult sites, like Killing Kittens - this is a "swinging" site, but female led, in that the woman has to make the first move etc.
There are others, like Fabswingers (can be a shock to the system!), and Adult Friend Finder (which is a paid site).
Alternatively, "normal" OLD sites can be used - just make it obvious what you are looking for in your profile.
Beware that there are a lot of married men on (all of) these sites.
I'm sure whatever you decide to do, you will end up spoilt for choice! Good luck!
