I know it's a ridiculous question but I have read of studies which concluded that exposure to BPA in womb and during first 1-3 years of life have been linked to a number of issues such as: poor emotional regulation/impulse control, asthma, obseity, PCOS and erectile dysfunction.
Is there any definitive evidence out there proving that there is an impact on sexual behavior and/or development of the brain's 'gender'? I don't mean to be alarmist, but the idea that so much of my sense of self and behavior has been influenced by environmental factors kind of weirds me out.

No it isn't OP. Being LGBT is a consequence of upbringing.
>>7922492
Honestly that, as well as all the other xenoestrogens, plastics, birth control, etc. in the water supply and in our everyday lives is probably influencing everything too.

This. People are quick to criticize arguments on causality of GD but don't consider the fact that these things could be causing the brain to develop differently, hand in hand
Although one would expect a higher rate if that were the case
>>7922501
Absolutely. I can't help but wonder what the consequences are, for society at large. It kind of scares me but only becwuse it isn't clear to me.

Indeed. I am no scientist but it sounds like a certain level of exposure to certain plastics during pregnancy and infancy may lead to actual changes in the brain. I realize that LGBT predates some chemical that was designed in the late 1800s but still, I don't know what to believe and I think certain industries profit from silence from consumers and researchers.

No, there's really not. It is pure speculation on this point. It might be worth researching, but I think it far more likely that psychological imprinting during the early years of puberty determines these things. Basically, your first sexual "events" (not necessarily even any kind of sexual activity, but just noticing other people's bodies in a sexual way) imprint on you and determine your sexuality for life.

Upbringing can definitely be a major factor for imprint events.

I've seen lots of stories of people acquiring kinks earlier than puberty and I would assume orientation is acquired earlier still.

I doubt such stories, desu.
