I use this because it is phthalate-free and very affordable. Among their many side effects, phthalates lower testosterone (in both genders). Any cosmetic products containing "fragrance" likely contain phthalates, while sensitive-skin and unscented products often do not.
I don't mind that the label says the product is for women—the label is purely marketing. It is more manly to maintain my testosterone while using a "women's" shaving gel than the other way around.
