While understanding or embracing our sexual desires might be a challenge for women in a society that paints our sexuality as needing to be focused around men and their needs (even women who aren’t straight), there are challenges for men and non-binary people as well. Everyone can feel shame or discomfort around their sexual desires based on the messages they received growing up, the messages communicated about sex in their adult life, and their own internal dialogue. 

There are different blocks to fully embracing your fantasies. I would say the two most common are lack of awareness of fantasies and fear or shame around the content of the fantasies.
