mylegsRmines,
I can tell you from a man's point of view. ANYTHING you do to intiate things in the bedroom will be welcomed with open arms. I understand your being shy and I think that anything you do along these lines will make the gesture all that more memorable to him.
Your husband would have to be a real clod to laugh at you for doing anything creative in this area, no matter how small. I don't think that would happen. If you feel that insecure about it or don't know what he might like. Try writing a letter or something like that asking what some of his fantasies might be, letting him know that you are a little shy about even broaching the subject with him. Or if you don't want to do that then I would suggest reading some of the articles online in some of these women's magazines. There's always something creative in there.
If there's something about yourself that you're afraid to reveal about yourself after 16 yrs then I have to tell you. DON'T BE. Especially if it's something that may add spark to the love life. If he has a problem with it then you are right back to where you started. Nothing ventured, nothing gained.
Trust me, it doesn't take all that much to push your husbands buttons. Sorry, us guys are really pretty simple. I heard a commercial on the radio recently that made me laugh. I don't even remember what the product was, but, it talks about how complicated women are vs. men. It has this woman's voice that comes on and says, "oh, I love it when you kiss me there, oh, and there is good, oh, and I like it there too, oh, and that's a good place. Then the guy's voice comes on and says, "Oh Yeah! That's the place!".
I gotta tell you, it's not all that more complicated than that. Anything you suprise your husband with will be met with absolute delight.
As Nike says, Just Do It!
Good luck and let us know how it turns out.
