I own Kingdom EdP as well as the Shower Gel and I'm not gay.
It's marketed for women, but that's Guerlain's Jicky also, which is quite masculine IMO. There are a lot of fragrances marketed for women and are quite masculine and the other way round.
I probably will never wear Kingdom in public or at work, because I just don't want to be seen like that.
Actually it doesn't match my personality at all, but that's not what fragrances are all about.
I prefer it before bedtime or on sunday afternoons. Definitely a keeper. There's also a limited edition available, which is quite similar and could be seen as a Kingdom fresh version. I didn't like that one as much.
Haven't tried MyQueen yet.
