I'm 50. I've used Tinder, Bumble, OKCupid and Feeld.
Bumble is the one where women have to message first, but there are just as many strange men there as on the other sites (some exactly the same.) I've had dates from there, and from Tinder and from OKCupid (which I don't really like the interface of, but I did get a few dates from, so kept with it.) Very briefly signed up to Match but hated that interface. Haven't tried Hinge, PoF or others.
I only signed up to Feeld to see what it was like after someone talked about it, as I'd never heard of it, and my profile has the bare minimum needed to use the app. It's designed as a kink-friendly dating site, so might not suit everyone, but I've had some good, normal dates off it, and have met a particularly lovely man there, who I'm starting to think might be my last first date, so...
My summary would be it doesn't matter which site you use. Go for the one you find the interface easiest to use.
Whichever site, you will still get interest from men looking for a quick shag, who will talk about sex early on, who will ask if you want a threesome or will peg them or whatever else. It happens on all sites. You will also find lovely men looking for long term relationships who can do decent conversation on all sites, but you have to filter through a lot of chaff to find the wheat. You need a thick skin and patience, because there will be a lot more swiping no than swiping yes.
