A cowboy is sitting in a bar when a woman comes up to him and says, "Wow! Are you a REAL cowboy?"
He says, "Well ma'am, I ride a horse, I herd cattle, I rope cattle... I reckon I'm a real cowboy."
Then he says, "So you like cowboys, do ya?"
She says, "Oh don't get the wrong idea, I'm a lesbian." He says, "What's that?"
She says, "It means I like women. In fact, all day long I think about nothing but gorgeous naked women.
Kissing them, touching them, having sex with them... anyway, nice meeting you."
And away she goes. A couple minutes later another woman comes by and says,
"Hey, are you a REAL cowboy?"
He says, "Well, ma'am, I used to think I was, but I just found out I'm a Lesbian."
