What helped me was spending time in groups where I was in the gender minority and also making female friends I wasn't interested in dating. If you're not just looking for sex, it helps to learn a bit of what it's like to be a woman and you're more likely to get that exposure in a space where women feel comfortable. I might be biased because I realized I related to women more than men and transitioned but I see so many sad guys that would make good boyfriends if they got a little more experience being around women.
