How long will it hurt after having sex the first time?

This is normal. Your hymen is definitely broken, since it was painful and you have been bleeding. It will take at least a week for the soreness to go away, and it will hurt a couple a times when you have sex, because your hymen is still sore from your broken hymen, and it has cuts inside. So when the penis enters the vagina, it reopens those cuts which causes the pain. I went through the same exact thing with my bf, hon. And I was so scared to have sex with again, after enduring the pain. Tell your bf to be gentle with you during foreplay, and don't make sure he don't finger you too roughly, use KY jelly also.
