I'll use my favorite case study as an example: Alpha Soldier Guy. He was all wolf while having sex. But minutes later, he would be bringing raw brownie batter (one of my favorites) into the bed so we could snuggle, watch a movie, spork, you get the idea. Granted he wasn't Mr Talkative. But he showed a softer side that made him totally hot, only because I knew he was already wolf. See what I mean? And he was never once arrogant or cocky. He didn't need to be. He was just confident.
I think BF would agree with you completely. Especially the line where you say that he could be soft because he was already wolf. The point BF is trying to make is that women won't care for men or find them attractive when they're soft and unable to be wolf, IOW, when they need it most. I think he's right and wrong. In the long run, nobody, male or female will be able to maintain attraction in a relationship under those conditions. In the short run, most reasonable loving people can and do cut others they love some slack UNLESS they are angry or resentful for other reasons.
