Well sexual orientation is down to sexual dimorphism in the brain and more specifically the regulation of specific sex hormones to decide your sexual orientation which again has been tested on rat models when you gave a castrated rat E2 he all of a sudden started to have a sexual desire.

You can't test this shit on humans because of ethics and shit, so rat models are the closest we have also we can't look at a rat's thoughts let alone it's interpersonal views on things, but we can look at the arousal in the brain we can look at who they pair up with.

Also, I don't understand where you're getting this idea that sexuality is fixed if sexuality is genetic and genes regulate your hormones in your brain if you switch around those hormones than you can switch sexuality it's possible you can make a man gay by taking more progesterone this is why body builders who take tren claim they go gay.

Although you're right on this, retarded solutions like external influences on the phenotype through conversion therapy or shaming some 1 doesn't work. Like, how can it ? Most of your behavior happens through internal mechanisms, but I'm not suggesting that, I'm suggesting changing the hormones in your system to match a desired result.

In the absence of everything all you have left is your genes and the only thing that matters is your genes really so reverse engineering the mechanisms for your genes what I'm referring here.
