Well, speaking as a bi woman, I know women can be tough about sex. I was on and off about it in my younger years. Generally I was more into it when ovulating, but then of course, there's more pregnancy worry.
I have been much hornier since I started peri-menopause at age 42.
My gf is still of child bearing age, and she's hard to get in the mood. sigh... (just one reason I am poly and need/want/desire a man in my life)
Maybe you need an older hot woman lover!
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
