What's the difference between regular chamois cream and women specific chamois cream? If my partner also rides, are there disadvantages to both male and female users sharing the women specific type?
In many cases, the difference is just related to the scent.
However, some standard chamois cream has menthol or some other "icy hot" chemical, which some women find a bit "strong" for their sensitive bits. Many women's creams use something milder, like peppermint oil.
