Here's hoping This Is Us showrunner Dan Fogelman takes these comments on board as the show gears up for a second season. Sex is an important part of any relationship, and Kate and Toby shouldn't be denied that opportunity because of their size. If This Is Us is truly serious about being an example of body positivity, it'll touch on all aspects of their lives. It's not just about waving Milo Ventimiglia's bare butt around (not that we'd ever complain about that).
