Tears (cuts) on my vag

I look at my vagina all the time checking cause I have anxiety I’m dealing with it. Last night I had sex with my boyfriend and this morning when I looked I had these tear (cut) looking things by the opening of my vagina they weren’t there before we had sex and i also looked not on inside my vagina but at the top of the opening on both sides it looks like something but none of it was there before the sex.
