A cowboy is sitting in a bar...

A woman sits down next to him and says, "Are you a real cowboy?"
He says, "Well ma'am, I ride a horse all day, herd cattle, rope cattle, brand cattle. I reckon I'm a real cowboy alright. So... you like cowboys, do ya?"
She says, "Oh, don't get the wrong idea. I'm a lesbian."
Cowboy says, "What's that?"
She says, "It means I like women. All I think about all day is women. Beautiful, sensual, erotic, naked women. Nice to meet a real cowboy though." Then she gets up and leaves.
Another woman comes and sits down. "Say there... are you a real cowboy?"
He ponders for a moment and says, "Well ma'am, I used to think I was. But I just found out I'm a lesbian."
