brizzle, yes, but it's true!
I think people assume that, if they don't notice homophobic behaviour, it's just not happening. And of course it is.
A fairly small minority of homophobia I've experienced has been your stereotypical stuff - people yelling at us or threatening us or whatever. But, totally well-meaning people do really awful things all the time. Today I was in A&E with my daughter, and the experience stood out, because it's one of the very few medical appointments I've had since she was born, when my sexual orientation wasn't an issue. It was a constant issue throughout my DP's pregnancy, during her labour, in recovery, with the health visitor - everything! It is just routine to have people say 'who's her mummy' or 'oh, you don't look like a lesbian!'. It is routine to be told I can't be her mother if I didn't adopt her, or that they can't share medical details with someone who isn't a family member.
I really notice the stark difference between friends who are straight and friends who are not. The first group are always really sympathetic when I mention minor discrimination, but also really shocked, because they believe it's unusual. The second group just know it's normal.
It doesn't mean the OP should marry a man, of course not. But it isn't helpful to belittle her experiences of discrimination either.
