I think there's nothing wrong with it as long as the writer actually puts effort into the plot and characters. I've noticed a lot of slash stories are poorly written to the point where they're basically porn without a plot or just flat and forgettable stories with characters that stray too far from the fandom.
I don't find it disgusting - it's good as long as it's written well. How is Penana 'not the right site' for it? There is never a 'right site for something'. A good writing site has everything - from slash to fanfiction and people willing to give good constructive criticism.
