Earrings from the lobi store are restricted to females as well. Its pretty dumb and sort of sexist. Yet my male Ferasan has two sets of double earrings, you can even have a nose ring. Bajorans also favor earrings, and I know a few human males with some. Same for skirts, sure maybe we don't want to run around in a summer dress but a kilt would be nice.
Its simple stuff like this that Cryptic is losing money on if they both expand these features and make them available to both sexes. It really puts quite a damper on alien race builds as well because who is to say you don't want earrings in your culture. Many males throughout many civilizations have had bones and or other implements pierced through their skin. To boot some of these aliens may choose to be neither male nor female.
