help please!!! first time having sex!!

Holly
Hi everyone, I lost my virginity about a month ago and the first 2 times it didn't hurt and I didn't bleed, I think because we did foreplay before.
The past two times we've gone straight into it and I've bled and it hurts at first. Not too much but it was more than spotting. 
I was just wondering how long it will take for me to stop bleeding when going straight into sex? Thank you xx 
(I'm 17 btw and we do use protection x)
