In my opinion, it can be muchh more difficult if you are gay to find someone. Instead of waltzing up to a member of the opposite sex and having to only basically confirm that they are 1. single and 2. into you, which can be done pretty subtly, you have to add the extra question, and it becomes, 1. Hey, are you gay? 2. Cool, are you seeing anyone? 3. Nice, maybe want to go on a date? And so there's three chances for something to get in your way.
My first crush once asked me if I was a lesbian, and, on the spot, I just stammered that I was not, which is true, but in my nervousness I didn't elaborate, and so that was as far as that went. Oops!
I knew a woman in my early college years who was an open lesbian who had somewhat of a hard time in the romance department, not because she wasn't a great woman or attractive, but because she was so extraordinarily charismatic and quick to flirt that unarmed straight women were likely to jokingly flirt right back! And then she never knew who would seriously be into her and who was just winding her up, since only the extreme minority of those women were actually ones with whom she could have a viable relationship. She once gave me her number and I held onto it for the longest time, wondering if I could somehow make this work with my religious views. The answer wound up being no, but I sometimes wonder what would have happened otherwise.
