Okay, so here's how I see it:
Option 1)
jmf is truly seeking advice, but is too ashamed / unfamiliar with folks around here / a dork to say what it is he actually wants
Option 2)
His gf is also on this board
a) jmf doesn't want to say what it is he wants because he doesn't want to embarass his gf
b) he is looking for a passive / agressive way to bring up his kink
Option 3)
He's a 14 y/o pimply faced youth (hence the idiotic "yo mama" jokes) who is just looking for a reaction
I'm thinking either Option 2b or 3.
I think one of the reasons why people are so curious as to what your kink is (besides, of course, for the amusement value) is because the advice will vary depending on what you want. I mean, asking someone to lightly tie you up is a lot different than asking someone to tie you up and beat you to a pulp.
Bottom line: Without knowing you or your gf, the best advice is what everyone has said. Talk with her. (Although, preferably not in the heat of the moment. That has "bad idea" written all over it.
