The Aquarius sex position involves the penetrative partner standing while the receptive partner is in a back bend with their hands on the floor and their legs wrapped around their partner's waist. The penetrative partner supports the receptive partner's hips and waist throughout to keep the receptive partner from tiring out or losing their balance.
We completely understand if this position is inaccessible to you due to disability, chronic pain, or the way your body moves and we recommend having conversations about disability and access needs prior to attempting this.
