@apriljune12 you're straight so you wouldn't understand the need to come out when your sexuality is the default...
It's not just about sex and liking cock. Is that what you think gay people try to convey when they come out? That they don't want their family and friends to be under the illusion that they DON'T like cock?
People come out because by default people are assumed straight unless told otherwise.
People SHOULDN'T have to come out, and hopefully some day soon they won't, but in the society we live in it's important for a lot of people to at least let their loved ones know what their sexuality is as it does differ from the majority.
Which seems more and more ridiculous as time goes on, but when I came out it felt like a big deal and something I needed to do. 10 years on and I don't feel the need to tell anyone after the initial coming out to my family and friends.
