Yeah. So true. My sister and my brother know what I'm into. Guilty for getting my sister into gay relationship novels! My mother on the other hand that's a definite no! I remember once I had a manga out (Crimson spell) and my mom came in picked up the manga looked at it the whole time my butt was clenched and put it down and walked away. I was like " don't open it! Don't open it!" I know my dad saw one once.... He don't talk to me for a week. Oh well. He's over it now...
lol... in Latin American culture there are several novels that talk about incest including one of the biggest masterpiece "100 anos de soledad" (100 years of solitude) from Gabriel Garcia Marquez were an aunt falls in love to a nephew in every generation of a family... if interested you should read it, pretty interesting.
