Irritating!

So a few days before ovulation time I start to get zits on my lady bits. Sometimes its and ingrown hair others are just pimples. I have been test and no std's as of now. I clean every day and I only shave randomly. Does anyone else have this problem? Do you have a solution? My man isn't bothered by this, and they are only painful if they get popped and are healing. So just looking for tips or tricks. Thanks ladies!
