I don't hide anything. My parents know what I do. If anything I clean to prove to them I'm a clean person after all, haha. Sex toys and everything should probably be in a discreet place anyways, but as for everything else...shoot, I have a giant basket of condoms next to my bed that my parents have BOTH seen. But they know almost everything I get up to. My dad enjoys lecturing me about what he sees as "delinquent behavior" even though it's all stuff he did when he was 22--which is a point I frequently make to him.
Nah, my parents are two of the most understanding people in the world. Right now I'm wearing my Queer Pride Week t-shirt and I'm sure if I walked into their house wearing it neither of them would be shocked and/or comment on it. I am so proud to say my parents love me 100% no matter what--sex toys, condoms, alcohol, marijuana, Christianity, and sexual ambiguity besides.
