1 The butterfly position or modified missionary
"With the woman on her back and
her hips on the edge of the bed, the man penetrates her while standing.
She then puts her legs over his shoulders and tilts her hips slightly
upwards. This gives a wonderful angle for cervical stimulation with deep
penetration that can produce some intense vaginal and uterine orgasms.
With more shallow penetration, a man can stimulate the anterior vaginal
wall to hit the G-spot."
