Plus be a generally positive and enthusiastic person outside the bedroom.
You do have to be realistic and accept that you will never get as far as the bedroom with a lot of women. They are human beings, not a Thunderbirds puppet. But once you get intimate with them, it's easy getting them to like you a lot. Just get good at sex,which is easier than learning to play the piano, but more difficult than playing a Triangle. And be a well adjusted adult outside the bedroom. Simples!
How do you think you'll do?
