That is true, male homosexuality if generally frowned upon,  but I sometimes wonder if that revulsion doesn't have some basis in the fact heterosexual men feel it's their prerogative to sexually pursue women and can't stand the idea of themselves being sexually pursued and assume gay men are inherently attracted to straight men.  Plus there is the age old shaming as exemplified by Jewish armies of old who would sodomize their militarily vanquished to drive home the point the losers were no better than women.  Male sexuality and it's expression can be interesting to say the least.
