I read that Bowie was claiming to be gay since 1969. He actually admitted that he would say that. [Seemingly he appeared cool] He said he claimed he met his wife, because they were both biblical with the same man.
Though before my time I will never understand why the whole androgynous movement in music took off. When I look at people like Prince, David Bowie, or Grace Jones I get a very uneasy feeling that I cannot describe. Especially when I look at Prince.
Bowie denied it later, though said it was a joke between him and his wife to always tell people they were banging the same dude. He later said it was a mistake to spread these sorts of claims, as they were not actually true.
David liked Bowies
