Why all the fuss about coming out? I don't really care about someone's sexuality unless I want to get in their pants. I'm sure most people don't want to hear whose pants I want to get in anyway.
To me, a gay person walking around professing their love for dicks is exactly the same as pathetic frat boys walking around wearing fedoral breast inspector shirts. If one day you come home with a guy, I'm sure your parents may want to have a chat with you. But there isn't really any reason to tell them you plan to have naked penises other than your own in your bed. It is like you are asking permission to do such a thing.
Sure, it does make it easier to meet gay people if you are out. But most of the time they are just the frat boys of the gay world.
Remember: if your sexuality is one of the most important parts of your personality, you may want to sit down and have a think about just how much of an interesting and worthwhile person you are.
I don't mean to sound negative. If anything I hope someone reads this and gets something positive out of it.
