Sixty Nine

Fifty Shades of Grey is a horrible reference for writing sex. Try anything by Evie Hunter instead.

There's more to sex than licking and thrusting. Also, harder and faster isn't always a good thing.

Incest stopped surprising everyone since Game of Thrones.

Don't advertise your book purely on sex. Like, if your description reads: "SEX FROM THE FIRST CHAPTER", I will want to punch you in the face.

You know you have a shitty character when she's really popular and really "slutty" but is a virgin because she only goes to third base.
