Man on Top
Everybody starts out in this so-called "missionary position": man on top, woman on the bottom, face-to-face. It's where we were when most of us lost our virginity.
This position gets a lot of bad press these days because it's "old-fashioned," or perhaps because it's "patriarchal." Actually, there's nothing wrong with this position; it affords excellent support for thrusting, close intimate contact between lovers, and is an ideal position for conception. The woman may lie with her legs spread wide and to the sides, or may draw them up to her chest. In either position, the man cannot reach her vulva for manual stimulation although in the first he can reach her breasts.
Woman on Top
Occasionally in adult movies one may see this position done with the woman facing away from her partner. While the sensations giving to both partners in this position are very different and may be very stimulating, most people feel the loss of intimacy involved is not worth the difference.
These positions all mirror the "on top" positions, except that the partners now lie on their sides on the bed. They can be achieved face-to-face, at an angle or from behind.
The one difficulty with this position face-to-face is that someone has to rest their leg atop their partner's (usually the man's leg is on top of the woman's lower leg); after only a few minutes of keeping still or resting in this position, the partner whose leg is below may feel cramping, pain, or a sensation that the leg is "falling asleep" due to a cut-off of the blood supply; however, many women find that if a continual rocking in-and-out movement is kept going, blood will naturally flow into the lower leg and the position can then be sustained in comfort for the duration of intercourse.

What about the shower?
The shower, as well as the swimming pool, have their disadvantages. For one thing, lubricant doesn't last very long in environments of such overwhelming volumes of water. For another, usually the only position available is standing, with all of the attendant problems of differences in height. Another common problem is that the floor of most bathtubs is very slippery, especially if you spill lubricant on it! However, it's frequently the only place other than the bedroom where both of you are likely to be comfortable and naked, especially in winter. Don't let all the "problems" listed here stop you from trying out what could become one of your favorite places to make love.
Having sex outdoors has its own challenges and rewards. Many people feel that sex outdoors is closer to nature; others feel it is more illicit, "in full view of the whole sky." If you're going to have sex outdoors in any position other than standing, plan ahead of time to bring a blanket. Avoid using bug spray and sun block until afterwards-- both taste awful. On the other hand, sunburns on your genitals can be excruciating; take care.
Having sex in strange places is a turn-on for many. How strange a place you want to make love is a matter of some concern of course, since outside of the privacy of your own home, having sex in full view is likely to arouse the interest of the local constabulary. Getting arrested for public indecency is likely to catch the attention of your employer as well. Plan any such dalliances in advance and scope out your intended rendezvous point for possible problems, interruptions, and routes of escape if necessary. And whatever you do, put your used condoms and wrappers in the trash can; stopping litter isn't just good citizenship, here's it's a matter of sheer good taste.
