R.D.
I can't believe no one responded to this yet!
No, *I* have the drive, my husband is the one who's lost his (but he's also 12 years older than me)... but that affects me too. If he doesn't feel like he can 'make it work', and I know it's not my fault but I still take it personally, then *I* feel unsexy, and it turns into a vicious cycle.
To break the mold: be spontaneous. Set a date (for yourself) when you're going to be the first one to make a move. Think outside the box. If you normally have sex in the bedroom, maybe get things going in the living room, bathroom, or kitchen. Get sassy ;) Do something out of the ordinary: grab his butt, kiss the back of his neck. Make HIM want YOU.
I used to want to be a sex therapist, and I'm really open and unembarrassed about this kind of stuff. If you'd like more info, send me a PM... good luck and HAVE FUN trying :)
