"Something I'm particularly passionate about is choices in childbirth," said the birthing photographer and mother of two, from Victoria's Mornington Peninsula in Australia.
According to Gallo, women in mainstream birth cultures are limited with their pain relief options - with an epidural, gas or nothing at all being the main choices.
Gallo described her first birth as "highly medicalised" and she underwent an epidural that left her feeling out of control of her body.
In her second labour, through masturbation she was able to have a birth free of medical interventions. It lasted for six hours as compared to her first labour which went for 45 hours.
Her blog post has opinions divided, with some sharing their own stories and others making inappropriate or insensitive comments.
"It's not a sexual urge whatsoever," she said.
"It's my body saying 'hey, natural pain relief is where it's at'. It's about exploring your options and exploring your choices in childbirth and taking ownership of your experience on a physical and emotional level."
