The great myth of ‘gay sex’ is that it occurs between two big alpha males. In reality, usually what happens is that weaker, submissive males offer themselves for, or are simply coerced into, sex with an alpha male, to use the wolf-pack analogy.
Wolf-packs contain both patriarchal and matriarchal hierarchies, which makes them even more interesting, but for now we’ll concentrate on the male, patriarchal side.
There is a phenomenon called ‘situational homosexuality’. In this, weaker males may sexually pair with stronger ones, if women are not present or available. One example of this is ‘prison sex’ which occurs in all-male prisons (we’re only discussing male homosexuality here. )
