My husband was VERY attractive to me. His hair was receding just a little bit so I know he would have had a bald spot eventually had he lived. After we had children, he got a little pooch in his belly for a time because he had as many cravings while we were pregnant as I had.
I found his hairline very sexy. I found the pooch endearing and beautiful. He started to get crows feet and gray hair on the sides of his head. He was beautiful. I was very attracted to him physically. I understand what Pink is trying to say here, though I'm sorry it triggered you guys. What kind of a relationship would I have had with my husband if I was not attracted to him? Just because people say they want to be physically attracted to another doesn't make a person bad.
I would say, ask the guy you are engaged to if he finds you beautiful. Does he find you sexy? I would imagine he would say he does to both. Would you want to be with him if he didn't? What I found sexy and attractive in my husband would be different than what another finds sexy and attractive and that's okay.
I hope you are able to work through this. We are all beautiful people.
