tell tale signs

One night a man and a woman are both at a bar having a few beers. They start talking and come to realize that they’re both doctors.

After a few hours, the man says to the woman, “Hey…how about if we sleep together tonight. No strings
attached. It’ll just be one night of fun.” The woman doctor agrees to it.

So they go back to her place, and he goes in the bedroom. She heads off into the bathroom and starts scrubbing up like she’s about to go into the operating room. She scrubs for a good 10 minutes. Finally she goes in the bedroom, and they have sex for an hour or so.

Afterwards, the man says to the woman, “You’re a surgeon, aren’t you?”

“Yeah, how did you know?” says the woman.

The man says, “I could tell by the way you scrubbed up before we started.”

“Oh, that makes sense”, says the woman. ” You’re an anesthesiologist aren’t you?”

“Yeah”, says the man , a bit surprised. “But how did you know that?”

The woman answers, “Because I didn’t feel a thing!”
