Are you the Low Drive partner? Please respond and tell; what has worked for you to boost your "desire." I've heard all the theories about what it is and how it works, but personal experience is the best info...
Exercise, losing weight, getting out and enjoying life again have done wonders for me. But that's with H out of the house. Hot to trot and no place to race. I have no idea what could convince me to want to have sex with him again.
Do you like your H? Do you love him? Stop looking for the whys and just do it. If you want to increase your drive, I think the best way to do it is to increase your activity. I think the more you do it, the more satisfying sex you have, the more you want it. Get some toys if you want and let him use them with you.
I posted somewhere once that I was being stingy with my "O". Like I wouldn't give him the satisfaction of satisfying me. If you like him and you love him and he loves you, I would just say go for it. Get the kids out of the house, if you have any, and just let loose.
Some of the best sex I had with H was after I had found out that he was having an affair. I thought that if I just turned up the heat, he would come around. I actually found myself wanting sex a whole lot more- more than he did even. Now, I'm not sure if I'm really warped and it was a whole lot of wanting what you can't have, or if increasing the activity increased my drive. But something did it. So I know it can be done.
Each experience in life has formed me, become part of me, made me stronger.
