Do YOU think sexuality matters in dating?

Hello folks,

So recently I came across a debate that nobody can agree on. A lot of people say when they find somebody attractive then sexuality matters a lot? But obviously say you are gay, you aren't going to approach somebody straight romantically even if you wanted to and even if you were attracted to them. WHY? well because primary you don't want to make them uncomfortable and sexuality is "private". But surely if you are looking to date it's better know somebody's sexuality before you make a move.

Assuming it is a NON- HOMOPHIC zone and the country is safe for all, surely it's not an issue. And also heres another dilema...
If you look "straight" how do you put yourself out there without people liking you for your sexuality? It's known that hookup culture doesn't work for geniune relationships if that's what you are looking for, for example say you don't meet them in a sexual setting e.g a club and you want to get to know them romantically, how is that even initiated amongst gay people?

What do you think? How can one develop a genuine romantic connection putting stereotypes aside?
