Actually, the number of people who are truly asexual is non-existent. They are not asexual, they just either bury their desires deep or keep them totally under control.
And even if there were, those numbers are so small that to use them as a barometer is not very realistic. The number of destroyed lives, families and homes is too great to ever let that poison into a house or a life.
There are more asexuals than you think. I know a couple, both genders. Not a couple together, I mean a couple of asexuals. People who just have no desire and actively don’t want to have sex. Period. Both even tried hormones but it didn’t work.
I don’t understand it but neither do I understand exactly how it feels to not feel like the gender you have.
Look. I don’t like the fact that porn now may be too much, and I fear the VR + attachments porn soon available. I despise child porn and I am very concerned about sex slave porn.
But there probably has been some form of porn since a caveman first found a piece of charcoal to draw on a rock wall. And everyone fantasizes, whether they look at videos or not, so what is the difference, really? No one’s sexual fantasies are about platonically eating tea and toast with their fantasy person. Aren’t the thoughts “porn” too? (And of course the books, etc)
