Thanks, Alex, I think this topic is really interesting. There are so many aspects which just don't get discussed in society at large. I often feel like our understanding of sexual orientation is in its infancy.

A few points: You have to separate out some percentage of guys who are secretly gay or bisexual and just represent themselves as straight for obvious reasons. The internet is an easy, anonymous outlet for their sexual desires.

But, as anyone who reads through LPSG can see, there are a number of guys who are strongly attracted to women but are also turned on by cocks to varying degrees (often starting with their own). Some only want to look at and talk about them, others want a little contact. I don't think "bisexual" is really the right word for them - theirs is not the true attraction to both men and women that bisexual people describe.

Systems like the Kinsey scale and our LPSG percentages are a start, but they don't fully or correctly account for the various aspects and nuances of sexual orientation. Like many have said, "labels" are inexact at best and worthless at worst. Also, a careful look at all this suggests that whatever genetic roots may underlie sexual orientation, they are overridden in some way by our psychological make-up: the variation that we're talking about could not come simply from the presence or absence of a gene.
