I've found myself increasingly attracted to TS, to the point where I want to experience one. I'm sorry if I come across as ridiculously naive, but where could I find such a creature? Are there sites that specialise in hookups with TS? I'm Brighton based btw.

Have you tried doublelist,maybe worth a try.
just put Brighton as your location.

If your happy to see a TS escort then try Birchplace, you can use the search box in the top right to find members, in the list on the left Brighton lists 24 members . Quite a few photoshoped pics so just bear in mind that what's on display might not match reality, most of them are obvious though, very soft focus and oversized cocks. As for the experience of being with a TS, do it, it's awesome!

Save your money.

Just groom a gender confused, porn addicted teenage boy in a Discord server, get him to dress up like a little slut and then fuck him in a cheap hotel room.

You know, like normal people do.
