Here's an update on my experience:
I went to a doctor who is a friend of mine after I had told him about the wet, warm senstations.
After a cursory exam, he asked me if I took any chlorestral medicine, I told him I take Pravachol, but only when I can afford it...and I buy it in Mexico. I told him I take it every other day to "stretch it out". He asked when the sensations started...and coincidently enough, they started about the same time I started taking the Pravachol again.
