41 year old female in constant heat?

Menopause means you haven't had a period in 12 months in a row. What you have is perimenopause, which is the time before menopause when you have irregular periods and sharp fluctuations in hormones. Perimenopause can last for years. You probably didn't want sex from 35 to 41 because your hormones, especially testosterone, were at a low ebb. The ovaries functioned less and less, until your pituitary gland (the "master gland"), which controls ovarian functioning, sent out a massive signal to jump start the ovaries. This caused the ovaries to overproduce hormones and the amount of estrogen and testosterone in your body shot up a lot. Your body had likely become hypersensitized to these hormones due to having low levels for awhile. So the hormones gave you a large kick in the libido. You can expect such fluctuations for awhile. No telling how long.

well i think it can be menopause it is just different for every one my mom had the same symptoms but without the whole sex thing and then ive heard of other people that they had the same symptoms as you did you really need to go to the doctor and tell him about it just so you can be sure :) good luck
