> “There's this phenomenon called homohysteria, which is the fear of being perceived as gay that I think really, really is destructive for men's friendships,” she says.

I see this claimed a lot (usually from women), but it doesn't seem true to me. It is true that men are less likely to form new friendships as adults than women, but I don't think it has anything to do with being perceived as gay in most cases. It has much more to do with the ways men and women socialize. Women also seem better at retaining friendships when they move, by calling and catching up with their old friends, while men tend to let old friendships die. Obviously these are generalizations and there are plenty of exceptions in both directions, but I think the basic pattern is true for the two groups as a whole.
