Believe it or not, people who love to romance and people who love intimacy and are more likely to have children are not the same people. People of earth signs and air signs love to romance more. People of water signs and fire signs love intimacy more and are more likely to have children. People who love to romance may be dating their whole life without ever settling down to have a family.
Also, a lot of men of earth signs, men of fire signs who are close to earth signs, and men of air signs who are not close to water signs, like to pursue younger women, the younger the better for them. It may be due to the fact that they like to be challenged and they enjoy the thrills of winning. This kind of men only enjoy getting women to fall in love with them. They do not enjoy the companionship of the women they conquer.
On the other hand, a lot of men of water signs, especially Pisces, prefer older women. I am not sure why.
