Suggest Remedy For A Bump On The Vagina

I have a red bump by my peehole. I ve never had sex so I don t believe it could be an std so I thought it to be a ingrown hair but it hurts so then again I thought maybe it wasn t. It s like right beside where I pee and it doesn t bug me unless something bumps it and it s the size of a dime. It somewhat looks like a blister.
