I found an article on this subject at imyours blogs, its quite interesting. Excerpts from the article follows:
When it comes to new relationships, a big topic is roaming the heads of both individuals; sex. More specifically, new partners are often thinking when should I have sex with him/her, as this is very common. Though it may be stereotypical to say, men are often much faster to want sex than the female in the relationship (99% of the time would be a good guess).
