Pain with sex (dyspareunia) is a common symptom for women with endometriosis. There are a few things that may help improve intimacy: understanding of the problem, better communication, and a little experimentation.
Understanding of the problem
Stretching and pulling of endometriosis lesions located behind the vagina and lower uterus is usually what causes painful sex.
Discuss with your partner the extent of your pain, and how it affects you. Discuss your feelings, frustrations, or fears with them.
Some women find that they can plan sex around their cycle or even experiment with different positions.
