From this female's perspective, pink on a masculine man is hot-t-t. It has an effect similar to seeing a beautiful, feminine woman in, say, racing leather pants and motorcycle boots. The "butch" quality of the clothes only accentuates her femininity and creates an exciting visual dissonance. Similarly, pink on a mature man whose skin tone it complements makes him seem more manly to me, not less. And it suggests that he has the confidence to "own" his sartorial choices. My father, in the 1970s-80s, used to wear a pink Brooks Brothers suit that looked amazing on him. (He was in his 60s and 70s at this time). It worked with his skin tone and coloring, which was very, very pink and light. Interestingly, my skin is more olive-toned, and I can't wear pink at all. It doesn't bother me; I actually prefer the color on men, anyway.
