Yeah. I suspect that's part of it: it is individually difficult depending on how hard you make it for yourself.If you make "coming out" a big deal, then it will be.
There is some peace of mind that comes with making sure that everyone knows, though, so I wouldn't go as far as to write "coming out" off totally.
Individual circumstances make it an impossible question. It's too hard to theorize what would happen with equally-situated people because none of us have the exact same families, friends, attitudes, etc.
The best thing that can be done is to not make it hard for yourself. Know that people's reactions to you don't change who you are, and shouldn't change what you want. Realize that no matter the consequences, you, too, are doing good: one, for yourself if it makes you feel better to have it out there and two, for all the BHMs/BBWs who doubt that there are people who prefer them the way they are to know that you, in fact, do hold that preference.
