What does the emoticon :P mean?

I emailed a woman (my own age) a dirty joke and she responded;

"Dirty Old Man!" :P

Does that emoticon mean "I like it, tell me more." or "That's perverted, don't talk to me."

Hmm..neither.. it means a person sticking out his/her tongue..it could mean that theyre joking..based on what she said i think she meant youre a pervert but put the ':P' to make it less harsh maybe :S
