It's a problem with OKCupid. It's a free site so you get a lot of people that join it on a lark and are happy to potz around with the idea of going out on a date but when it comes time to show their face in person, well not so much.
I've been really persistent with it and put up with the abysmal success rate. I've ended up with about a dozen dates in the past year and a half, so it is possible. But persistence is the watchword if you're going to get anywhere with it.
Do you post that you're trans? Oddly, I found I got way fewer responses when I did, but the responses were higher quality.
You're young and you're cute. You will find someone. Keep at it.
