Bird, I think by this time your parents should be a little suspicious of you spending all that time in the bathroom. Just be straight out with them. “Mom, Dad,…I had a little dick maybe is due to genetics.(Mom looks at Dad and Dad lowers his head in shame). So you must of been wondering why I have been spending all this time in the bathroom or my room. No, I’m not on drugs. I’ve, I mean, well…I’ve been doing these excersises, that suppose to make my thing bigger and it’s been working. (Dad looks in interest) Well, I want maximum veinage…(Mom says, “Oh my god, my son has turned into a freak”) No, Mom, damn, this is why I could never talk to you….(You leave room)..Mom looks at Dad, “This is all your fault”…Dad follows you to your room where he finds you crying, “Hey son, now what kind of exercises are you doing”…
*So at the end of the day you’ve become better friends with your father and tother you can fix the privacy problem.
