To get into the Doggy in Space sex position, the receiver should stand in front of the sex swing, or be positioned if they cannot physically stand. They then place their upper body into the sex swing - taking care to arrange the sex swing straps where they will be most comfortable for supporting body weight.
The penetrating partner then steps behind the receiver, and lifts up the receiver's legs on either side of the penetrating partner's body. [The top should check for pain and discomfort at this point.] As the penetrating partner does this, the receiver leans forward onto the sex swing straps to make the sex swing support their upper body weight while their partner supports their lower body weight. The couple can then enjoy intercourse.
A lot of disabled people may have difficulty trying this position, so please have a conversation around it first.
More About Doggy in Space Position
This sex position relies on the strength of both partners to be pulled off. The penetrating partner must have enough upper body strength to support the receiving partner's lower body. The receiving partner must have enough core strength and upper body strength to hold themselves semi-vertical through the entirety of the position. While the sex swing will help support some of the body weight, don't be fooled: this can still a very athletic sex position. It is okay if you and your partner are unable to perform these positions, as a result of disability or body strength.
Your choice of sex swing will drastically change how much support the swing provides - and your own bodies will need to make up the difference. A sex swing with thinner, smaller straps (like the one shown in the illustration) will rely more on your own strength to support your upper and lower body. A sex swing with longer, thicker straps (like the Door Jam Sex Sling Special Edition or Door Jam Sex Sling) will provide more support to the abdomen while using a sex swing. With a bit of creativity, a full-support sex swing like the XR Brands Extreme Sling can also be used to provide enough support to reduce most of the body strain of this position.
