i do believe that kissing has been labeled a sin  by the vary people who over-sexualized it in the first place;
two lips
brushing
pushing
rubbing together like the skilled hands of a masseuse on another person's bare back.
like painting my nails
or watching baseball
or wanting cherry flavor instead of grape
my want to kiss
another person
male or female
is a desire of the flesh:
a sin against God.

how do i discern the the good from the bad?

this must be why religious people go to such extremes, live in such strict communities, allow themselves to be enslaved by a culture created generations before they were born.

they are confused.
