A commonly made mistake that deserves its attention. When a guy gets a boner while lying simply in his underpants, this is a clear signal of that it’s showtime. No matter how sexy it seems to passionately rip off those underwear make sure to lift the elastic waist band over the little fellow. Otherwise our friend will get caught in the waste band and experience a painful penis whiplash.

Believe us when we say that the smacking is neither sexy nor pleasant.
