Paper cut on outer lips

Hey ladies this might be TMI for some of you. So on the outer lips of my vagina right by the sex hole I have two little cuts that look like paper cuts. It hurts to wipe with dry toilet paper and it does not burn or itch or anything else. I have had this before but never two. I usually feel it when inserting tampons but now I'm not on my period and its there. There is no pain and I've done std tests coming back negative. Also another weird thing is I have stringy egg white discharge which I usually never have had. I don't think. Lol does anybody know what this could be?
