Hi Janine,
This forum is very open. Great place to ask questions. You will get real answers.
As for sex drive, it took about two months or so before my sex drive returned. I think this was mainly before of hormones, in balance. Plus my body was healing, WLS in major surgery. Fast weight lost will do crazy to the human body.

I am almost 5 months out and the sex drive is normal for me.
As for Vaginal Looseness. I have not notice a differents after losing 60 pounds. The vaginal wall is wrap in muscles. There are Kegel Exercises. Go to this website.

On a brighter note, sex is easier and tons of fun after losing 60 pounds, hubby seem to be HAPPY.
