Strange fantasy?

I'm a 34 year old man, very happily married. Here's my question. Is it strange that I have this fantasy about my wife dressed like a schoolgirl? I have this fantasy about her wearing one of those little short skirts, button down blouses, pig tails, etc...and then...well, you get the idea. I've seen out on the net that there are lots of sites about this type of fantasy(you almost trip over them even if you're not looking LOL) so I guess I'm not alone, and shouldn't feel strange about it. But here's the thing. I've asked my wife to wear a short skirt in the bedroom for me before(not being more specific than that) and she's said "sure", and later even teased me with the idea while talking about other things...but she's ever actually done it, even when I've mentioned it repeatedly(this is going on 3 years since I first asked now). She's never said she didn't want to, so I'm not sure what the deal is there. So, if she might not be willing to go even that far(possibly, and just doesn't want to tell me), how do I ask her to fulfill the full fantasy with me, without it sounding like I'm some sort of pedifile or something?

Help.

You can rest assured that your fantasy is not strange and definitely very common! I would get on this a.s.a.p. if it is something you feel so strongly about. You are married and should be comfortable enough to express your desires without any fear that your wife would think any less of you, especially if she is not opposed to dressing up in the bedroom. Remember she is not psychic and maybe assumes that the skirts she's currently wearing are short enough. And while this may be true, you still need to express your desires explicitly so that she gets it. Express your fantasy again and suggest shopping or ordering her outfit together. The experience before fulfilling your fantasy will most likely bring you even closer together. Who knows, maybe she's always wondered what it's like to screw a teacher? Ask her what her fantasies are as well. Start talking and shopping and you will get your school girl after all! ;)
