Are there shuttle hints you can wear or do to let other guys know you are gay and available?

I want to meet guys, sometimes I see a guy thinking I would be attracted to but am not aggressive enough to ask if they are into guys, so is there something I should look for or something they wear or I could wear that says it’s ok to approach.

 

If he's looked down at my crotch, I'm starting a conversation.

 

I guess the real question would be is are you actually attracted to guys or just the cock? Are you bisexual or gay?
Either way, why not go to a gay bar. I'm sure it wouldn't be very hard at a place like that to find an open-minded guy who's willing to help you out with your thirst for cock
