I don't, I have sensitive skin and using anything like that would probably throw it out off balance and I'd get thrush

I just wash it with ph balanced tea tree shampoo and don't put anything else on it

I also get shaving rash which is why I don't shave it because I'd rather have pubes than have it look like it has a venereal disease so I just tidy or trim and I'd rather have pubes anyway because I'm an adult

My vagina getting wrinkly is the last thing I'm worried about I worry more about upsetting its natural balance and getting thrush, a rash or ingrown hairs

Need any other disgusting details?
