How can I ease ovary pain and also prevent it during sex?

Positional adjust. The ovaries are "suspended in place" by ligaments and its' connection to the uterus. During deep penetration during intercourse, such as lying on one's back, the ovaries can be struck and the pain is similar to men being struck in the testicles. "women are the superior sex" and that position can limit penetration and allow for more control of "the event".
