This is so brave of you to write this and such an amazing educational experience to try and write erotica from so many different perspectives.
I steer clear of romance at all in my writing because it makes me embarrassed but you leaned into it so kudos to you!
I agree with the kindle sales on amazon being low. I have 8 books in different genres on there and $7CAD this month is the most I’ve seen in a long time (from a novel that took me 2 years to write).
