Women avoid having sex, afraid that their partner will find out about their hemorrhoids. A hemorrhoid is an enlarged vein in the anus (it's also called a varicose vein).

However, when there is constant pressure or other factors restricting blood flow, the veins become inflamed. Poor blood flow may cause a blood clot. That results in a painful, swollen, protruding hemorrhoid.
