You could try Wattpad, FictionPress.com, or AnArchiveOfOurOwn.com. (My daughter uses two of the three) You still still have to create a profile at any of these sites, but it's not quite as arduous as creating a blog. Keep in mind, any content you put on the interwebs, though copyrighted as yours at the time of publication, is subject to piracy (My published content has been ripped off by Wattpad authors a couple of times, which makes me wary, but then again, Margaret Atwood chose to have a story published exclusively there. There is good and bad, to sum up.). Still, it can be a really good way of honing your skills and getting useful, almost immediate feedback. There are always trolls that flame everything--I'd advise you not to allow anonymous reviews--but there are some thoughtful readers out there, too.
Best of luck to you
