What is the difference between 嫐 and 嬲? According to mdbg.net, both characters have a meaning of "to tease":

嬲

to tease / to disturb


嫐

to tease / to play around with


Are both of them primarily used as synonyms for "tease"?  Or are they commonly understood to have the connotation difference of "bothersome" vs. "playful" teasing?

If the latter is true, as a comparative Google Image search of the two characters suggests, I'm rather curious about the etymology of "man-woman-man = bothersome" and "woman-man-woman = playful".  But my main question is about current common usage of the two.
I'm afraid there is no "common usage" of these two characters in contemporary Chinese. They are used only in colloquial dialect.

For exapmle:
我嬲都不嬲你 I don't fuck with you

You may hear this sentence, but you can hardly see it in the written Chinese.

To find out their difference, just consider them as pictographic characters, then what is the difference between teasing scenarios "Man-Woman-Man" and "Woman-Man-Woman"? You can imagine it, right? 

Edit: Perhaps 嫐 is more sexy(coquettish) than 嬲, according to 《康熙字典》: “娆，嫐也。”
