I think I just did explain it for you. Thirst is natural, necessary, and absolutely a physical need/drive. I’ve learned I can drink different drinks. Sometimes I want a coffee (sort of bitter drink) and sometimes I want a Coke (sweet drink). Ugly/pretty.
You’re not getting me. Homosexuality is so disgusting to normal heterosexuals, you’ve got to be naturally twisted to get into it. It’s not like choosing a different beverage.
