I've never used match.com, but I suppose you can just write it on your profile. I think that's the best you can do, so you don't waste your time and energy on people who won't accept you.
I'm on okcupid, and I do say I am trans, and ask women not to message me if they have any issue or discomfort because of that, but that I am ok answering awkward questions if they just don't know or understand what being trans .
While I still haven't found the one (in part because I think this may not be the best moment in my life to find her), I have gotten some good response!
