Dear baebae, cute name. Welcome to PC. I have no qualifications on a professional level but I have life experience. I googled endometriosis symptoms and what I saw was pain... pain...pain. Is it really a constant pain? That in itself would diminish my interest in bodily attraction in a body that just keeps hurting.
When I have more energy in the body, I feel more. Maybe then you would get a sense of what or who you are attracted to.
So how would you get energy. Exercise or walking, youtube has beginning yoga or Qi Gong (Michael Costa has some basic movements. Consult your doctor before starting any exercise routines outside your comfort zone.
There are forums that people deal with gender issues and sexuality issues at forums.psychcentral.com
