I have a sebaceous cyst in my pubic area and another on my inner labia that I recently popped and some pus came out and now it's gown . Now today I found another cyst on my inner labia ..am unable to squeeze as it protrudes inward into the mucosal area. The one on my pupis seems to be going away. What could be the cause of all of these cyst all at once. My sexual needs have not been met lately and I find that when am aroused the cyst itches a little. C OULD A LACK OF SEX BE THE CAUSE FOR THIS.
