One of the biggest advantages of this position is the fact that it allows for deep penetration or shallow penetration! The penetration depth can easily be controlled by how deeply the receiving partner's leg is stretched: Close the angle of the legs to reduce penetration depth or pull the knee even further back towards the face for deeper penetration.
As another advantage of this sex position, the receiver's genitals are easily available for stimulation from either partner. With both hands free, either partner can provide additional stimulation for the receiving partner through hand sex or sex toys. Depending on the positioning of both bodies, you may find that larger sex toys like wand massagers are a tight squeeze. You may need to select smaller sex toys -- like the Tenga Spinner, Wild Flower Enby 2, We-Vibe Tango X or Hot Octopuss Jett to avoid disrupting the penetration angle.
The Splitting Bamboo position, as shown, may not be comfortable for all bodies. The receiving partner's raised leg needs to be able to lift high enough to allow the penetrating partner enough space for penetration. This can be a deep stretch for some, and the angle required will be different for all couples depending on the size, heights, and penis length of the included bodies.
Experimenting with the receiver's body placement may help make this stretch easier or harder. If the receiver lays on their back, it will stretch the leg in a front splits position. However, if the receiver props themselves up on one hip, it will be reminiscent of the middle splits position. Most people will find that one option will feel better than the other.
