In a way, it is. Since humans were created to reproduce, when we love someone, we usually feel sexually attracted to them, as well as love them at the same time. But there's nothing wrong with this; it's just how we were made.
It's not. The term love can refer to a person you are attracted to, as well as your friends and family. I don't know about you, but I don't feel sexually attracted to any of my friends or family. 0.o The reason you make friends is because we were designed to help eachother.
...just my opinion.
