My thoughts on familiar Intercourse

Hi Everyone this is my first post. I am been want to post something for awhile now and finally I cannot hold my thoughts. I want to know what others think. I have thoughts of i****t is that bad? I mean growing up I would spy on my parents and watch my mom take showers, and fantasize about her naked body. I have even spied on my grandmother, brother, aunt, and cousin. I am a nudist and the only one in my family, no one knows that I am nor do they know that I like porn. I hope to raise a nudist family some day. I have fantasized about making love to my wife and daughter at the same time. Is this bad? or my mother in law and her daughter? or my girlfriend with her sister. Just different combinations. I want to know others thoughts.

sincerely
