Feelings of well being vs sexuality, I personally would go for "well being", first, and the heck with concentrating on the sex area.
But, that is coming from an approaching 50, woman, has been there and done that, soooooooooo . . . the sexual thing may no longer be the priority as it is with younger folks.
Most important thing, concentrate on yourself,be kind to yourself, even borderline, worship yourself, and put your mate's needs after.
Again, this is my own opinion, based on real life experience(s) in my life, not applicable to others.
I wish you lots of luck and healing with this all.
