You're quite right...as adolescents we may have engaged in some really "wacko" conversations.  You were fortunate to have a respected adult overhear you and help you assess your conversation.  Apparently Trump has spent his life surrounded by sycophants like Billy Bush who laugh at his crude jokes and encourage his lewd comments.  Therefore, he's never gotten pas that adolescent behavior and, as he became more and more powerful, made it a way of life. IMO, he's actually a very pathetic excuse for a man.
