Woman-on-top positions allow the woman to more actively control the sensations, both for herself and her partner. The man has limited mobility and the woman has control over the angle and the depth of penetration. She can also control the speed of the thrusting to suit her own pattern of arousal. These positions are comfortable for women with large partners or where the woman is pregnant.
One option is a simple variation of the missionary position. The woman lies on top of the man and guides his penis into her vagina. The couple can vary the position of their legs to vary the sensations.
In another woman-on-top position, the woman can sit up. This gives her a full view of her partner, and gives her partner full view of her breasts and genitals which can be extremely arousing. By taking all of her own weight she can control the penetration to her liking. Her partner can caress her breasts and clitoris.
The woman can face away from her partner. In this position he can see and stimulate her buttocks and anus and she can stimulate her clitoris while at the same time controlling the thrusting.
