I definitely agree! First off, men and women have completely different chemical makeups. Mens active chemical hormone is testosterone and females is estrogen. These hormones not only affect a person's physical body attributes but affects men and women's mental and psychological thinking.
I don't believe there wouldn't be a book out that has been as successful as it has if this wasn't true.
Women, by nature, tend to be more nurturing and sensitive. It's also a proven fact that they typically speak more words/day then men.
Men are typically more risk takers and competitive by nature. They do not speak nearly as many words/day than their female counterparts do.
Some men work at a job where they speak to customers over a phone or in person all day. By the time they get home, they are ready to relax. Their significant female companion wants to chat and know how his day was. Because their male companion has already exceeded his words/day, this can cause major conflicts.
Most women need to feel a connection to someone before they are ready to have sex with them. Men were made to spread their seed and really do not need a connection before doing the dirty with them. *I am not saying men are not faithful or don't feel a connection, just saying they don't need to feel a connection and are usually ready for fun in the sack a lot faster then females.
