Husband and i had sex, nothing out of ordinary. i now have vaginal tears. intense pain after 5 days. even hurts to walk. what can i do?

Herpes? Yeast?: When sex is traumatic and causes tears or other sores, almost always there is obvious pain during sex -- or certainly within a few hours, e.g. the next morning. Appearance of sores a few days later, especially such painful ones, sounds like herpes or perhaps a rather severe yeast infection. See a doctor immediately, the sooner the better for most accurate diagnosis and most effective treatment.
