Ask them i guess although, i usualy find 99% of the guys in the bars that Gary and I frequent are gay so i dont really need to ask them

Of course you can always do what i did to several cute guys at the Florida show and say to them..

'What a waste'

When they ask what you mean say..

'That you are straight'

They will either say they arent straight or will shrug it off because it wasnt done in an insulting manner
