Here are some suggestion experimenting with the following sexual positions:

Position if you are new to sex:

Missionary Position:  In the missionary position, the person with a penis  is on top and take the dominant role. The other person who is on bottom assumes the passive role.  Each person is lying down, stomach-stomach, face-to-face.  It is one of the  true methods for intercourse. This is a great position. The person on top has a lot of control over the degree of stimulation that they get and the person on bottom can easily increase their sexual pleasure by masturbating while simultaneously having intercourse. If the partner on top is especially coordinated, she/he could also help masturbate the person on bottom. Some of the techniques used to create an intimate environment are eye-to-eye contact, guiding your partners hip movements with your hands, massaging your partner's neck/back, nibbling the other person's ears, necks or lips. And of course, whispering something that only your partner can understand.

Position for couple who are looking for new position:

A slightly more technically advanced position, than the basic missionary position  for the creative couple only. The person on bottom and the person on top switch leg positions. The person on bottom closes their legs. The person on top straddles the legs of the person on bottom. Visually, it looks as if the person on top is doing a wide-legged push up. The benefit of this position is simple: for the person on top, additional stimulation to the penis and for the person on bottom, additional sensations on the inner thighs.  Expect to sweat a lot, it is a great exercise.

Position For a woman who wants to have sex  for the first time:

Woman on top is recommended for women who are having sex for the first time because it puts them in control of the situation. The woman is in a position to engulf the penis  at her own rate of comfort. Of course the other person has some control of the situation too because they are constantly talking/sharing feelings throughout this whole experience. In this position, the person on bottom should tilt her or his hips, back flat on the ground. This allows for an angle that often many women enjoy. In this position, the person on top often lies atop with her legs stretched out or bent. Sometimes, she may sit straight up and slide up and down. Many women really like this position because of the added genital stimulation.  In addition, men can stimulate their partner's vulva (and/or breasts and/or other body parts) with their hands or women could masturbate themselves while having intercourse. Many people on bottom find this particularly pleasurable because of the added visual stimulation of seeing her breast. 

Position for slow motion sex:

This position is for those people who enjoy slow motion sex. The angle for intercourse is not conducive to vigorous thrusting. Position the person with the penis sits cross-legged on the floor. The woman sits on top of him, with her legs straddled around him. They are sitting face-to-face. This creates a perfect opportunity to hug for a few minutes and be intimate. Be careful that you do not fall over! Sitting on top of each other and maintaining stability is a formidable task for most people. Some people prefer facing the same direction. This is preferable for those who feel less coordinated or embarrassed. You do not have to face the other person. Great chairs include rocking chairs, kitchen table chairs and, of course, the chair in the office. Sex on a chair makes for a good study-break.

Position for quick intercourse:

A true quickie, for the super coordinated couple-- try standing and having sex. In the ideal world, both people would be of similar heights, or one person could be strong enough to lift the other person to reach the right level. Women need to tilt their pelvic, so that the vagina is forward, and easier to access. The person with a penis either need to squat a bit or have the woman be on a small stool. However, if the woman is taller, then her partner may need to stand on the small stool. This type of intercourse seems to work well on staircases in an office building, down a dark alley, and other such forbidden places. I highly recommend at least one person wearing a skirt or some other such clothing, which will allow for easy access.
