I am gay. And I don't want the rose gold iPhone. It is soft pink to me. I've seen the rose gold Apple Watch, along with the rose gold stand for he new iPhone, and I do not like it. For me, it is an option for the female market.
If guys want to rock it then brilliant, go for it. No one deserves to be judged for the colour of the phone they use.
Having said that, I think some people are kidding themselves when they say they've bought it coz they like it when really it's because they want people to know its the newest model. I'd have more respect for people who just outright said that than pretended they were buying it because they're some new 'modern male'.
