Sometimes bleeding continues through the first couple times you have sex. Like iam1butterfly said, the vagina also tightens up if you haven't had sex in a while.
The vagina tends to tighten up if you hadn't had sex in a while... as in the 2 years that
you mentioned. So, pain and bleeding isn't at all unusual for the first few times.
Next time, try using a lubricant and ask your partner to penetrate slowly and gently.
