Especially in the more difficult version, the “Oyster” requires a lot of strength and flexibility. In the simple form, the man sits on the bed with his legs open, while his partner sits on his lap and puts her legs over his elbows so that her feet are in the air. She can support herself with one arm on the bed and sling the other around her loved one. In the sophisticated version, he kneels in the heel seat, while she squats, sits on his lap and introduces his lingam. The man embraces his beloved by the hips, supports her on the back and pulls her close to him. Her legs stay wide open. She can hold on to the neck of her partner or support herself with her hands.
