You may notice that this site does not refer to either of these products as being for women. There are two reasons for this. One is that I don't want to discourage anyone from learning about pStyles or menstrual cups by referring to them as being "for women only." Since they benefit a sizable portion of the population I think it's important for everyone to know they exist. The other reason is that while women make up the majority of pStyle and menstrual cup users, they are not the only ones. Trans-men (female to male transsexuals) might use one or both products and biological men might use a pStyle if they have a medical condition or body piercing that interferes with their ability to stand up and pee.
