Hi,
Welcome to ehealthforum,
If it was your first time intercourse, then the bleeding that you describe could have been due to hymen rupture and should subsided within 48-72 hours time. Vaginal tone can take some time to relax (the tone and tightness becomes laxed after regular intercourse). Having adequate foreplay and lubrication helps relaxing the vaginal tightness. Visit your doctor/gynecologist for further evaluation and assistance and rule out possibilities like vaginismus, vulvodynia, vaginal spasm, etc.
Take care.
