As a straight female RPer, who came into RP not looking for romantic plot threads and feel into SEVERAL by accident, I can tell you that the stories and the players are out there. You may just need to look outside certain circles to find it. A lot of it is networking with players, meeting their connections and sometimes just walking up and interacting with folk in game. I had my character literally fall over someone in game and it led to a long term plotline. Mind you, I usually get "Wow I don't usually get such great response from walkups!" but .. heh.
Read people's cards, send them a tell and have your character run into them. Same as in real life. Just put yourself out there and you never know.
That being said I KNOW LGBTQ+ characters are overrepresented and that it's hard for male characters to get attention. I've seen it and heard it from so many players. So it can be tough, for both sides. You just gotta just keep at it. It helps to RP publicly. One of my current RP friends stalked my RP and now we type at each other a lot. Find those weird connections.
