I agree with everyone. A big part of the Lenny relationship has always been about their physical attraction to each other. The dance between 4A and 4B , for me, has been great to behold. I miss seeing evidence of that strong attraction. I've never seen it as one-sided either. Penny is into Leonard big time, contrary to some of her jokes.
But I've always known that the relationship is so much more than sex. Never doubted that in spite of the Nerd gets the Hot Girl jokes which the writers are so attached to.
Through the years Penny and Leonard have developed a strong friendship, whether they were a couple or not. . They care about each other, help each other, comfort each other, and share a full life together, alone and with their friends.
Having the chance to see all the facets of this relationship would be wonderful- the love, the friendship, the teasing, the fighting, the caring and sharing, the ups and the downs. There's so much more the writers can explore. Sounds like they've taken a look at a few things so far in the new season. More please.
