Well it's because of how Mashima has been handling these thing like it. How many times has Natsu seen Erza naked or Gray seen Lucy naked. How many times has Erza blushed to Natsu. How many times has Gray blushed to Lucy and so on. It's so common even among non-existing pairing that it feels so unnatural like FTGM said.
