Not that I enjoy gratuitously sexual
I have heard that punting is the term used to describe the act of a woman anally penetrating her (male) partner with a some variety of strap on phallus device or another. Considering that many many men of all sexual orientations like having their anus stimulated, this is considered to be a more or less heterosexual act by the fact that a female partner is doing the punting.
While this term is more or less unofficial, I believe that it originated from an issue of Savage Love (a weekly column available on the Internet among many other places) that appeared in early May 2001 -- and that it was the first time that sex guru Dan Savage had heard of a single term for this act.
I think this is a fitting term for several reasons: first, when I make a mental picture of what this act must look like, the word "punt" is a pretty fitting caption to it. Second, the word also alludes to the gender role reversal not only because it rhymes with a (particularly nasty) euphemism for the female genitals, but also begins with the letter "p", an obvious reference to the penis or phallus.
