"First you need to stop seeing it as a binary (being gay isn't a bit that gets 'flipped,'"

Are you as gay as I am? I had NO disposition towards men until I hit about 17 years of age. Suddenly, I couldn't stop dominating them in bed.

Something sure as hell 'flipped' in me to suddenly make me go from banging tons of girls in high school to dominating men almost exclusively.

And I've done modeling. I can pull whatever I want any day. Why did I suddenly prefer men? I still can't answer that.

Most people ignore women's general bisexuality, and confuse this by equating sexual preference as "complicated".

Not for men (for the most part, as in 99%). They either love vagina, and are disgusted by penis, or vice versa.

On the other side, most "straight" women, fantasize and experiment with the same sex, and to them, preference is usually on a sliding scale.

That all said, sexual preference is further confusing when we have a large subset of straight males, being attracted to very feminine transsexuals, like Bailey Jay.

To me this means male sexual preference is holistic, meaning if you pass as a woman, but have a penis, you may attract many straight males, who would gag at the idea of a well toned and very masculine male.

Even if the masculine "man" was a woman passing as one, with a vagina.

  They either love vagina, and are disgusted by penis, or vice versa.

In ancient Rome, "It was considered natural and unremarkable for men to be sexually attracted to teen-aged youths of both sexes, and pederasty was condoned as long as the younger male partner was not a freeborn Roman." [1]

Most people would agree that genetically, men haven't changed all that much in the last 2000 years or so, which lets us discount the idea that a genetic bit has recently been flipped.

That leaves the notion that sexuality is - at least in part - a social construction.

If little boys were raped in culture, they would likely replicate that behaviour no?

An example being pederasty of little boys in Afghanistan being common, similar to your example. Completely cultural and I would argue traumatic.

>They either love vagina, and are disgusted by penis, or vice versa.

I don't think it's normal for straight men to be "disgusted" by penis or for gay men to be "disgusted" by vagina. There's often social pressure on both groups to pretend that they have these feelings, but I don't think it's actually very common.

Hm... I'm generally attracted to (some) people who look like women, but that's just an assumption, open to change/dispute. I'm pretty sure I'd equally gag at the sight of that "pretty lady"'s penis...
