Your penis does not have the same pH as a woman's vagina and vulva, so do not use feminine hygiene products on your penis. Femfresh has a pH of 3.8 - 4.5, specifically aimed to be the same as the pH of the vulva and vagina. Normal skin is around pH 5.5, and soap about pH 7. In the same way that females can do damage to their skin down there by using regular soap (with a wrong pH), males too can damage their penis skin by using a wash with the wrong pH. Femfresh will make your penis' pH around about pH 4, which you shouldn't do.
Yes, I've used it for about 10 years now, NEVER had a problem, thrush etc...Safe as house's chaps...Just dont wash under the foreskin with it, that's always hit and miss for me
