In Melissa Broder's book So Sad Today, there's a lot of very explicit sex talk. In one paragraph she writes
I was fascinated with his uncircumcised dick. He was my first uncircumcised one. I felt like a virgin again. I wanted his dick to be dirty so I could taste what was under his foreskin aand really know him. But it was clean.
She also has a novel called The Pisces where the main love interest is uncircumcised.
I highly recommend her writing for anyone into a sexy read. She is so dark and funny and her twitter is fire.
