An old gay man goes to a female prostitute.

The man says, “I’ve only been with men all my life, but I’m a little curious what I’ve been missing out on. I want you to give me your best.”

The woman thinks this is a unique opportunity. She’s young and pretty, top of the line. The guy didn’t scrimp on cost for this experiment. She thinks she can probably turn him straight.

So she takes him into the bedroom and has him sit on the bed, then does a really sexy strip tease. By the time she’s standing there naked he’s looking at her with a huge grin on his face.

“Pretty impressive, huh?” she says.

“I’ll say! I didn’t know it took credit cards!”
