I love these kinds of debates, actually. I'm a huge fan of pushing boundaries--but even I have my limits and I would never ask anyone to read anything that made them uncomfortable (for me, that is Buffy/Giles fanfic--geez, he's like her father!). Don't worry, if this ever jumps to anything sexier than a cut scene, there will be a huge bold warning sign.
That being said--I would love to have you (Figgie) read my Kermit/Piggy love scene because as someone who is normally not into that kind of thing, if I could get you to read it as totally real and natural then I don't think it would freak you out. And then I would know that I'd really achieved something.
Besides, technically, these two are married. The only reason I balk at having Kermit outright admit he's waiting for marraige is because I don't want anyone to subconsciously assign any religious beliefs to him. (Let's face it, that whole 'in his own image' thing would really make it weird for Kermit to be a Christian and I'm not sure I could see him as anything else. He's like a tiny, green Mr. Rogers.)
