Is heterosexuality unnatural?

Of course, gays and other anti-man forces will vehemently deny this. They will claim that there is no pressure on straight males to be heterosexual, and that sexuality is ingrained and fixed and not taught and people do not consciously change or limit the flow of their sexual desires ... but that is all invalid ... of course, gays (i.e. effeminate males who like men exclusively), do experience it, but its an experience particular to these non-men who like men, because they fit into the heterosexual set up snuggly (of manhood=heterosexuality; and Queerhood=homosexuality).

This article from a western source, does hint at this pressure/ conditioning to be heterosexual, which both gays and other anti-man forces refuse to acknowledge, because of their vested interests.
