What more lgbt+ identities should include gender identity and sexual orientation to make my story more accurate /inclusive

So far I have a lesbian character and a bisexual character. What others could I add? It can be a gender indentify or sexual orientation. My characters are more than their sexuality they do have personalities, I just don't want to spoil too much but the lgbt part is integral to the story because it's a romance. One is an ambitious artist who has big dreams the other is a shy musician who doesn't really have much hope for the future. Originally I had something like 30 characters but it's been cut back to two but I think now I need to add more characters again.

Dealing with straight coworkers who are obsessed with sex and dating

I'm making a post here because I don't really know where to write this otherwise, really sorry if that's not relevant.

I've started working in a new place a few months ago and my closest coworkers are all women like me except for one guy and most of us are also in our 20's. Four of my coworkers are really, really obsessed with the topic of dating and romantic relationships. Two of them are mostly fine about it, like they're regularly mentioning dating apps and boyfriends but they're not overbearing about it either when I'm chatting with them one-on-one. The other two are really a pain about it though.

The first coworker is always badmouthing her former boyfriend and his new girlfriend, complaining about men but also how she can't live without them, gossiping about the men who work near us, sharing plans for her dream wedding, etc. She's also a huge fan of Taylor Swift, romantic shows like The Summer I Turned Pretty and romance books. Basically the kind of popculture stuff that I couldn't care less about. It's really hard to find something to talk about with her. Recently she has been acting kind of cold towards me and is avoiding to do work tasks with me when she can. So I'm afraid that she interpreted my indifference for her topics of discussion with me being rude towards her.

The other coworker isn't just annoying with the dating topic, she's straight-up obsessed with sex. She makes sexual innuendos almost all the time and is always bringing up topics related to sex, especially to our only male coworker. The problem is that she has branded me and another female coworker as "weird" and "puritanical" because we have shown that it makes us uncomfortable. My female coworker who is also uncomfortable about that is a very religious young woman and is now being treated as the "black sheep" of our workplace because she refuses to play along. Almost everyone talks about her behind her back and criticizes her.

My sex-obsessed coworker has said that I'm too "shy" and I need to "loosen up" with her help. She has this groupchat and I never posted anything in it because the only topic of discussion is just dating guys.

I'm afraid I'm going to be the next one to be treated like an outcast unless I try to get a boyfriend to have something to talk about with them or I participate in the sexual convos. I'd hate to have to do that but I also don't want to be excluded. I really don't know what to do...
