I was lurking in the Ladies Lounge and what someone said in this thread (about a Man's love for his aging wife being like his love for a loyal dog) really offended me.

While a woman's breasts may sag and her hair turn gray, that does not change that she is a sexual being. Any decent man would recognize that he ages too, and I guarantee when I get in my 50's my wife will be the sexiest woman in the world to me. Sexual attraction stems not only from the eyes but from the heart and the mind. Remember, your largest sex organ is your brain.
My parents still have it going on. The way my dad looks at my mom and way she looks at him tell me they're both still fiercely in love. Even though their bodies aren't the same, let me tell you that they're still undeniably attracted to each other both physically and emotionally. To suggest that my dad loves my mom as he would his pet is both wrong and greatly insulting.
About the erectile drugs also mentioned in the thread; a man's physical condition causes that problem, not his aging wife. If old women were to blame then the pills would make women look younger to him, not help men get blood flowing more in certain areas.
