good luck to ya sweat pea. i know when i was unhappy in my relationship i didn't want to have sex. now that i'm out of that relationship and losing weight...i am feeling much more energetic and my libido has definately inproved. i love having sex now. but i know that doesn't help you out any does it?? sorry.
but i definately think excersize has some to do with libido. and self confidence has alot to do with it too. i still get uncomfortable being naked around a guy but i feel more comfortable putting myself in that position. hehehe.
anyways...i hope your doc can help. and i definately suggest excersize. i believe excersize makes the world a better place to be...or at least a more tolerable place to be.
