Is there a medication to stop people being gay?

A couple of weeks ago, I received the following email:

Dear GB,

I'm new one and I'm not good at english. So pls understand my mistake. I do wanna ask you that What make gay and Is there any med for cure. Pls reply me. I don't have knowledge and I'm so afraid of being gay. And I would like to know the cure.
Waiting your reply.

When people send me 'Dear GB' emails, I usually want to think about their situation, and then write a reply online so that other people can give their views too via comments. But with this guy, I felt I needed to respond immediately, so I sent back a reply as follows:

I understood your English perfectly, so I hope that you understand my reply. Asking for a "cure for being gay" is like asking for "a cure for being tall". 'Gay' is just another attribute of someone, just like 'tall'.

When someone first thinks they might be gay, most people in that situation don't want to be gay, because for a while life is much harder. It's much easier to be straight because most people are straight, and it's easier to fit in than to be different. But when someone realises that they might be gay, they frequently have to reassess the whole direction of their life, which is hard.

The people who try to suppress their gay feelings usually can't do it forever. Perhaps it's possible for a while, a few years, even many years, but eventually it's too hard to keep hiding it. Once they accept that they're gay, and that there is no cure, they can move on and learn how to enjoy their lives being a gay person. Up to that point, most people aren't really happy, which is a shame.

It's also true that not everyone who feels attracted to people of the same gender is gay. It may just be a phase they're going through, or they may be bisexual and have feelings for both men and women. But again, if they just ignore their feelings, frequently it causes problems later because there's a part of their personality that needs to be investigated before they can achieve happiness.

I hope this helps. GB xxx

Does anyone else have anything else to add?
