Why is it that the only people who think being gay is a choice the people who are straight? I have honestly never met a gay person who said "You know something? I woke up yesterday morning and decided, yup, heterosexuality is getting boring, I might try being gay."
However I know plenty of gay people who spent many years trying their damned hardest to be straight (having girlfriends and making excuses that they couldn't sleep together because they were saving themselves) because people had told them they'd probably get AIDS and live a short and lonely life.
I'm one of them. Turns out it was all nonsense and aged 18, after sleepless nights of thinking about killing myself I decided to learn to accept who I really was. Turns out all my straight buddies were grown up enough to accept it too. I even managed to captain my university rowing team with complete respect from the rest of the crew. I'm now, at the ripe age of 32, 8 years into a monogamous relationship, living in a tiny village in the middle of England. I'm one of the biggest farmers in the area an my other half is a partner in a GP practice. It is not seedy, sordid or promiscuous. In fact it could be considered a little dull. But I wouldn't change it for the world.
There are uncountable decisions that I have made in life. Being gay was not one of them.
