It was strange to think that all the great women of fiction were, until Jane Austen's day, not only seen by the other sex, but seen only in relation to the other sex. And how small a part of woman's life is that.
When a clandestine couple kisses, it is much more likely that sex will immediately follow. This is because there is much more risk. Once you have kissed secretly, it is very difficult not to have sex. It would be impolite not to have sex. You have to show that you are serious about each other.
It's nice to have a lot of money, but you know, you don't want to keep it around forever. I prefer buying things. Otherwise, it's a little like saving sex for your old age.
