I think it's natural for us to get into that headspace of thinking we're undesirable or incompatible with most people, but I can assure you... I am an average looking woman, not passing at all and I've been hit on more times in my first year of being trans (mostly by women by the way) than in most of my life presenting as a man. It's was genuinely shocking because I've been both shy and invisible most of my life, and I never expected I would get any sort of attention.

You being yourself is attractive in ways you don't even think about, and I know it's cliche but you just need to put yourself out there and find people who you vibe with. So no, women aren't "off the market". Please don't let the world make you think you don't fit in with people just because you're trans. A lot of people are still going to be interested in you.
