Have you two tried Wattpad? They are free books written by amateur authors, but some are really good. They have a mobile app so you can read on your phone too. If you to choose to write a story, you can post it there. I have a few reading lists with good books (most don't contain a lot of sex though). Here are the links:

These accounts also have some good books on their lists:

I also have written two m/m books, but I dunno if they are your style (along with tags). The links are in my profile.
Wow, transmigration theme! I loved it in True Star and Kill the Lights (novels) and I hope this one won't disappoint me, too.
