can I have some advice on being "more gay"?

So my thing is a passive bi thing, my best friend knows I'm bi but everyone else thinks I'm straight, and after talking with a guy who I thought was fit, unfortunately I was "too straight" and this was a turn off for him. I think it's time to ease into my sexuality, if that makes sense? By becoming a little more gay I can soften the blow, also it would help when talking with guys. Thanks Edit: thinking like, more feminine.
