You are aware lifestyle goes well beyond having sex and children. There are plenty of hetros who have some of the weirdest sex you can imagine and many who never have children. There are also gays who do have children and families. People are all different particularly when it comes to sex. In addition to heterosexuals and homosexuals there're bisexuals, transsexuals, and asexuals and they have varying degrees of sex drive from strong to none.
It is not the label we put on a person that is important. It is the qualities of the person such as, empathy, creativity, passion, being responsible, kindness, leadership, honesty, integrity, and courage. These are the things that are really important, not who you love or how you have sex.
