It's interesting to read the two things you've posted in the last few minutes. There is your response to the Gattaca topic, and then this new topic that you've initiated. And reading this one throws a lot of light on your Gattaca posting, which was obviously written by a closeted man.
You most likely haven't and won't form any strong friendships because you've got something to hide, and this gets in the way of relationships, no matter if they be friends or family or even business. If you can't be fully honest, you can't be fully open. People pick up on that, and will always keep a certain distance... just as you do, too, in order to guard your secret.
As you mention in your Gattaca posting, I, too, would have taken a "straight pill" if there had been one available before I arrived at acceptance. I was going to keep my secret forever. But you know what? I was drifting further and further from the ones I loved, just to maintain my precious secret.
Long story short: No one has ever rejected me based on my sexuality. Not even the most narrow-minded people I know. Not in my family, not in school, not at work, not at the gym, not even at church. And you may be surprised, as I was, at just how many other people are guarding secrets, too. It's a universal thing... and folks generally are happy to have the opportunity to release these things. Simplicity's a wonderful thing. Being open and honest is about the simplest thing there is. Good luck with your journey.
