Epic Guide

Where is the sin?  Man and man? Man and little boy? Man and dog? Man and premarital sex? Man and lust?

My thought is that the only biblically sanctioned sex is between and man that is married to a women.

So at what point do you get to say what a sin is or notm but I guess choice is where sin is found. So why is our society quick to look the other way, and change the rules? Why not just not call something what it is?
