Cure for a tear in opening of vagina

Hello, two nights ago i had sex with my boyfriend for the first time, he is kinda big and im not use to that. Anyways afterwards i went to the bathroom and noticed i was bleeding a little. I can see where the blood is coming from and its not that big of a tear and its on the opening of my vagina, but here two days later it still bleeds sometimes, like here and there it will bleed some or it wont bleed at all where the tear is. What should i do to get it to heal??? please help!!
