Itchy down there & idk what to do

So lately I’ve been very itchy down there during school and at home I check down there every day to make sure there are no bumps or anything I am a virgin and I have never received oral or been fingered basically no one has touched down there or did anything down there but me so and I don’t think it could be herpes because I read that is a std unless I have it to myself I read that can happen to and I peel my lips so what if I had one and I like didn’t know and touched down there later on and gave it to myself ? Idk but coudlnt it be many other things it doesn’t hurt or anything it’s just really itchy any tips as well to make it sop and does anyone know what it could be ( it’s only the tops of my vag like the beginning part that’s itchy now the lips or anything just the top where the hair is supposed to be )
