It could be hogwash. While it certainly FEELS like being physically hurt, the emotionally mature person would very likely just go out and build/rebuild a life - without that person who hurts him or her.
I was in a sexless relationship and began to feel ugly. I thought there was something unappealing about me. I'm not a nympho by any stretch, but a normal, healthy woman with a normal appetite for sex and desire to share that with my partner.
