Vagina cut

I have had this cut (that’s the only way I can describe it) close to the entrance (the hole) of my vagina for almost 2 weeks now. I have left it alone, I’ve put Aquaphor on it... it won’t go away! It doesn’t itch or anything it’s just uncomfortable sometimes. Nothing last touched my vag except toilet paper! Nothing! I even changed toilet paper to see if that made a difference... Nope! Any suggestions?
