Asking for a blowjob at a gay bar?

Weird question... Basically I've been striking out with girls all my life. I turned 18 a month ago and I've failed with another girl in that time. I don't have romantic feelings to guys. Im just extremely horny and have no shame. I kinda want to suck someone off too...If I offered to suck someone off at a gay bar for a blowjob back would they accept most likely? I don't have any gay friends to ask or anyone with expierence about that.
