The problem with mha (over sexualization of girls)

Okay, so I love the anime and story, although it isn't flawless either... My biggest problem is the way it sexualized girls.. I've wondered what seemed off for me until I've noticed how BIIIG their 15 year old girl tits are.... Is it really necessary? I bet they'd look cuter and younger with lest bust ya know? Why cant the invisible girl just have an invisible suit either or powers to become invisible with it, instead of her just being naked... Also momo should just be a dude too so she's not as sexualized as she is (plus he'd be hot 0-0) or atleast change her outfit with a zipper on her cleavage ya know?--- Sometimes I wonder if the creator is like a p*do for this or sum----
