Not at all.
I'm a proud, out gay man, but I always thought that section of Facebook was stupid, so mine is blank. I'm not on FB to meet or hook up with people, so I don't want random guys messaging me. All of my contacts on FB are people I've met personally, with a few exceptions being folks I've been friendly with over the internet.
I don't even look at that part of their profile, because chances are that I already have an idea of their sexuality before friending them.
I'm of this opinion too. I haven't filled this section out on my own page because I have my younger cousin around and she's not yet at the age where I want her to be aware of my romantic choices. Other than that, everyone who I consider important in my life already know what and who I am, so there's really no need to advertise it to satiate other people's interest
