Are vitamin supplements good for health?

Almost every place that I go to, I see stores and stores just devoted to selling vitamins and more vitamins, and I was wondering what the benefits are of a normal healthy person taking vitamins daily. Are there any risks for a normal healthy person who doesn't take vitamins? Will the person taking vitamins' health be improved or have longer longevity? Will the person not taking any vitamins be as healthy as the person who is taking them? And also, what will happen if a person takes more than he or she should consume every day?


What can I do if partner finds doggie style painful?

1) My partner says she does not care for the "doggie" position because it causes her pain. I, on the other hand like to experiment and want to try everything. I guess I want more than just vanilla and she says if vanilla is great, continue to go for it. I guess I'm trying to sort out facts first. First, I know that only about 8 percent of women engage in this position. I guess I want to try it occasionally because the position gives me sight sensory as well as feeling. Anyway, I tell her I'd do anything she wants, anything to satisfy her in exchange for having sex in this position. I guess it's an obsession which becomes more of an obsession when it is denied!

Back to what she says. First, is that the angle is painful. She says the position is against the normal "curve" of the penis as it would enter in missionary position. Now on to the emotional side. What happens is that she will eventually consent but then because I feel guilty I jackrabbit and I can't enjoy it! What can be done to stop the pain she says is there? Is some of it emotional?

2) I like to have sex 'doggy style' more often than I could at the moment because my wife complains that it is painful. Is that common?


Is it dangerous to not drink water during sport practice?

I have a question about dehydration. I am an eighteen-year-old female and play on a varsity basketball team. We usually have two-hour practices in which we work very hard. Our coach does not give us water breaks, and usually by the end of practice, we have cottonmouth and are "dying" for water. It is horrible. Is there any way that not having water during that time can be dangerous? Sometimes the team can feel sick or weak by the end of a practice.


How can I exercise with bowlegs?

I have bowlegs. It is quite frustrating because I cannot do exercises that isolate and tone the thighs (lunges, squats, etc). When I do squats, my pressure/force comes from the calves and the knees, but not the thighs. Reason being is that the legs are not properly aligned, and pressure/force cannot go up to the thighs. It even hurts when I do squats because they involve bending the (crooked) knees. Are there any alternative thigh exercises?
