Hi,
Welcome to ehealthforum.
You can get married and have a normal sexual life. Do not worry about your past. There are pelvic floor exercises and other muscular exercises to help you tighten up the vaginal walls. There are creams and serums also available that you can use after getting examined by your gynecologist if needed. There is virginity restoring surgery available in which the hymen is repaired.
If you were an athletic personality in your school days, then hymen can get ruptured even otherwise due to rigorous physical activity (cycling, running, long/high jump, etc). So rupture of hymen and bleeding during first time intercourse is no longer considered as proof of virginity.
Go ahead with examination done by your gynecologist and discuss about possibilities that might be done to help you out.
Take care.
