Sorry for offending you, Branco, but unfortunately I have some news to break to you.
People masturbate. This includes your brother.
I know its a big taboo and that it is embarrassing to talk about, but I know for a fact that your brother whacks off, rubs a few out, has dates with Rosie Palm, Bashes the Bishop, etc. If he didn't, he'd be a freak.
Its okay to talk about here, we are all men and we are open minded here, and honest. Instead of fighting it, denying it, instead I suggest you embrace your homoerotic side and accept it.
btw, does anyone have any liquid body soap? Mine is empty.
