Is homosexuality a choice?

Putting a dick in your mouth is definitely a choice

Tbh, I kinda think it's just because it's " trendy " to be homosexual nowadays

I'd go with Redwing on this one. Not a choice, but not born that way, either. Something in the environment leads the brain in that direction, especially during the forming years.

Frankly, I think the open availability of porn might have something to do with it. "Some people" might turn it into a political issue about "indoctrination" or whatever, but I'm pretty sure it's as simple as kids getting the message that "___ is sexy" and internalizing it. They could see it on the internet, on TV, or it could be a recurring message they encounter while growing up.

No one really remembers this kind of stuff in their lives or notices when something is happening to them subconsciously, so by the time we hit puberty and adulthood we just say "I've always been like this." (Sexuality popping up before puberty is usually more clearly artificial.)

Of course, this isn't exclusive to homosexuality, and there's more to our bodies than just what our eyes see. I think it's an important factor, though.

There’s just too many gay babies for me to believe it’s a choice

Is being straight a choice?
Weird question.
You cant control what you're attracted to. If so everyone regardless of sexuality could easily be attracted to any type of person they wanted, would certainly make life nicer but that's not possible...

From what I've heard, prevalence of homosexuality increases with younger siblings who have older siblings of the same gender.

If it were a choice, then millions of gay christians would've chosen to be straight. They grew up believing that being gay was a sin and disgusting, so they felt totally ashamed of who they were and thought that God hated them. They would've given anything to be straight. They were even kicked out of their homes for it and a lot of them ended up committing suicide. If it were as simple as choosing to be straight then no one in their situation would've remained gay.

Of course, but that’s not what meant.

What I was proposing, was that, might not there be a biological determinant at birth, that has little to do with the parents’ genes or with the environment, and is just the way the baby came out at birth?

I don’t know anything at all about how genetics work so this may sound absurd.

Just because it’s not very heritable, doesn’t automatically mean it’s environmental, no? Meaning that anyone no matter of genes could have a wildcard kid.

Gmos perhaps? An abundance of soy in adolescent diet perhaps?

Of course not.

Sexual orientation is completely hardwired.

sex is a choice, no matter if you're straight or a homo.

Kinda yes but in most ways no.

It’s usually a mixture of both, as is the case with most preferences.

Born as gay is not a choice but going after a big black dick to get fucked is a choice.

If one views homosexuality as a disposition (as I believe it is), then it is a combination of both.

A disposition, correctly defined, is a preference towards a certain act over its other possibilities. So, of course, it seems, this applies to homosexuality.

Now, dispositions can be set or changed in two different ways: one is to be born with them, as, for example, most humans are born disposed towards food and against pain. The other is to place in one's intellect some knowledge that is against the current disposition, as in when one goes from disliking a food to liking it, or when one goes from supporting abortion to being against it.

In theory, homosexuality is the same way. Some people (though I would bet it to be few of them) are born with the disposition, while others (probably most of them) choose the disposition, just like with all other fetishes, which also boil down to dispositions.

There have been multiple repeated studies that show actual brain differences between "straight" and "homosexual" people (of both sexes). They have now identified these different brain patterns in infants; and are now awaiting to see how they develop as an adult to verify the relationships.

While they have not identified a specific gene responsible for it - the researches do believe that it is either due to a "regressive" gene or perhaps a somewhat common genetic mutation (compared to other forms of genetic mutations) that is favored by some other genetic factors.

It's likely going to take another 15 - 25 years of data to get good results from these studies. Then duplication of the studies will take another 20-30 years.

Sexual attraction itself? People are suggestive and desires can be fostered and trained in different directions over time by repeated consensual exposure as long as it's pleasurable, but not chosen 'in the moment'.

The genetic propensity towards homosexuality? Not to my knowledge.

Environmental factors, such as patterns that derive from childhood experiences and affective lack? Not easily.

What you do with your life, your thoughts, your words and your body and who you get into romantic/sexual situations with? Yes. Absolutely.
