Is this normal?

Kalypso
I'm 20 & I recently lost my virginity. Up to now I've done it three times and two of those times (one being right now) a few days after having had sex I've bled. But it's like the daily discharge and some blood, smells a little weird too. I wanted to know if it's normal. After a few days the bleeding stops. I'm really skinny and small and my guy's dick is pretty big, in case you had to know to come to a conclusion. I'd really appreciate some answers/advice.
