While I understand not wanting to see characters sexualized, this really isn't bad at all. She's in a bathing suit on the beach, attention isn't being drawn to any particular part of her body, and she's in a completely comfortable position. This isn't inherently sexual - people may perceive it that way, but that's them, it doesn't have to be you. It's cozy to sit on the beach on a nice day, look at it that way! Saying a women's body is automatically sexual is being the exact same thing you're accusing everyone else of being :P.

Also, you can't decide what will be where on the internet. I avoid looking at super sexualized ow art, you can, too.
