OMG. Why?
AGA, your ideas on sexuality tend to be unusual and extreme and you give the impression that everyone who doesn't do or see it your way is doing it/seeing it wrong.
Most people identify as gay, straight, bi or something. I don't think there's anything wrong with that. I think God makes us with a potential range of sexuality. Environment, experiences, and choice can influence your development within that range. Sometimes someone can fall in love with someone who is not their ordinary preference. You get that sometimes. Just like you sometimes get albinos but most of the time, people don't have pink irises. So as short-hand we generally say people have brown, blue, green, grey, or hazel eyes. It's possible to have other colors. It's possible to get your eye poked out with a stick. But we don't have to include those things in every conversation about eye color, IMO.
As a general rule, if you have a tendency to be attracted to (or lust after) a particular gender more than the other, you're probably best off with a partner of that gender. Just like if you prefer a particular body type, you probably shouldn't pursue people of the opposite body type. Assuming God gets involved in this kind of thing at this level, he's probably going to send you someone who is your type, since he made you in the first place.
I'm born again and doctrinally Evangelical, so I understand what you're saying about the lust thing. A lot of people do not share those views. I don't think it's right to hold people that do not share those views to the dictates of those views, personally. It would be like someone giving me a hard time about eating sausage for breakfast because their religion forbids the consumption of pork or meat. Or for not covering my head when I left the house or using electricity in the house. I can eat sausage, go around bare-headed and use electricity in the house with a clear conscience because those things do not violate my beliefs. So it is with those who do not hold to Conservative Christian standards on sex.
Personally, I've never fought the temptation to lust for a woman. I'm forty-two and I've only ever fought the temptation to lust for men. Generally stocky men with big butts. I consider that enough evidence to call myself straight and probably a chubby chaser. Not saying it could never change, but it's probably fairly unlikely at this point.
