Andromache Position

The man lies on his back. His partner places herself above him, crouching or kneeling, keeping her torso straight up. She perfectly controls the depth and the rhythm of penetration and can give a free rein to her fantasies of domination.
Pluses
The woman retains total control enabling her to be more confident and to find the right motions to maximize her pleasure. The man has his hands free to give his partner even more pleasure by caressing her breasts, her buttocks or her clitoris. This position stimulates the G-spot.

Minuses
The angle of penetration is sometimes uncomfortable for the man, or even painful if his penis bends.

Courtesan Position

The woman is seated on a chair or on the edge of the bed. The man kneels down to penetrate her. She then wraps her legs around him. Variant:
The woman can sit on a table or a desk, so that the man can remain standing.

Pluses
Comfortable position for the two partners. Allows good amplitude of motion and good depth of penetration. Can easily be practiced outside the bedroom.

Minuses
The feasibility of the position is very dependent on the height of the woman's support.

Missionary Position

It is the best known position, universally appreciated by both novices and experts. The woman lies on her back and the man lies between her legs to penetrate her.
Variant: A few cushions placed under the woman's buttocks change the penetration angle and allow a deeper penetration.

Pluses
Natural and comfortable position for both partners. Good freedom of movement for the man. The couple can look at each other, or kiss. Their hands are free for other stimulations.

Minuses
The woman's freedom of movement is quite limited. The position can become tedious, requiring a change: one should not abuse it!

Perfect Alignment Position
The woman lays on top of the man with her legs open to facilitate penetration. Once the penis is well in place, both straighten their legs so that the two lovers are superimposed in a perfect alignment. The woman can then start the stimulation by rubbing her body laterally and horizontally against her partner's.
Pluses
Very intimate position offering maximum contact between the 2 partners. The tightened vagina walls create intense sensations. Recommended for tantric sex.
Minuses
The depth of penetration and the amplitude of movement are both limited.

Position of the Rider
The man lies on his back and the woman, fronting him, kneels above him with her thighs around his. She completely controls the depth of penetration and the movement. She moves horizontally as well as vertically to maximize the stimulation of her clitoris and walls of her vagina, or to bring her partner to an orgasm.
Pluses
The woman has more freedom and is more active: she chooses the type, the speed and the rhythm of the motion. The man remains more passive and can concentrate on his sensations and pleasure, while caressing his partner's back.
Minuses
Lack of originality? You can always use a variant or try another position after a while.

Union of the Cat
Starting either from the missionary position or from the position of the Rider, both partners rock to the side, slowly to avoid unwanted withdrawal.
Pluses
An intimate and gentle position, allowing the two partners to look at each other and kiss, while avoiding domination of either partner.
Minuses
The amplitude of movement and the depth of penetration are both limited. There is a risk of involuntary withdrawal during the rocking.

Union of the Cow (or the Doggy-Style Position)
A classic position, universally appreciated for the excitement and intense sensations it gives to both partners. The woman is on all fours. The man, kneeling, penetrates her from behind.
Variant: The woman may make the position even more comfortable with a few cushions under her elbows.
Pluses
Very good stimulation of the vagina's front wall and G-Spot. Very lively and deep penetration. The man can easily stimulate his partner's breasts and clitoris with his hands. Very exciting view for the man, allowing him to indulge in his domination fantasies. The woman can easily fantasize about imaginary partners.
Minuses
Some women may feel humiliated by this position. The position can be painful for the woman if the penis bumps into her cervix.

Union of the Lovers
Both partners stand face to face, the man rubs his penis against his partner's vulva. After a few minutes of rubbing, the vulva opens naturally to allow shallow penetration. If the woman is shorter than the man, she can wear high heels or step on a support (such as a telephone directory under each foot) to reach the appropriate height.
Pluses
A practical position for impromptu sex in all situations. Good stimulation of both the clitoris and the glans.

Union of the Tiger
Starting from the Missionary Position, the woman lifts her legs to her torso. She can adjust the depth of penetration and the sensations by varying the angle of her legs. She may also take hold of her partner's buttocks and press them to her to increase the depth of penetration.
Pluses
By lifting her legs, the woman allows deeper penetration and can at least partly control her sensations. The man's pelvic bone brushes against his partner's vulva and stimulates her clitoris.
Minuses
This position requires suppleness from the woman, particularly if she draws her legs very close to her torso.

Union of the Elephant
Starting from the "doggy position", the woman lies down progressively so that the man completely covers her. She can leave her legs open to facilitate the penetration, or tighten her thighs to firmly squeeze her partner's penis in her vagina.
Variant: The man can straighten up on his forearms to relieve his partner a little and to penetrate her more vigourously.
Pluses
Natural and comfortable position for both partners. Good freedom of movement for the man. The couple can look at each other, or kiss. Their hands are free for lots of other stimulations.
Minuses
The woman's freedom of movement is quite limited. The position can become tedious, requiring a change: one should not abuse it!
