How do I use dental dams?

I've seen the recommendations. I've seen the suggestions for do-it-yourself workaround (cutting open a condom, plastic wrap... ). What I *haven't* seen is practical usage advice — how to place the thing effectively, how to overcome the limitations of losing direct contact, how to arrange things to permit vaginal penetration with fingers while still maintaining protection and so on. Best-practice condom use isn't perfectly obvious either, but at the most basic level it's pretty straightforward. If you want to build acceptance for barrier use during cunnilingus, it needs to be at least as clear and/or at least as well-documented.


Can I drink chlorophyll?

A coworker of mine was drinking a green liquid at the office and told me that it was "chlorophyll water". Neither of us are sure what the health benefits of ingesting chlorophyll are, and it's hard to find reliable info on the internet. Is this fad based in medical fact, or is it just a weird new drink to try?


Is androstenedione safe?

My question is about nutritional supplements, specifically androstenedione and its closely related cousins. I have a five-day-a-week workout routine, and I have been searching for a supplement that will give me the greatest benefit for all of that hard work. I am, however, very concerned about the negative effects of some of these unregulated supplements. My question then is, what kind of side effects can I truly expect from using one of the male hormone precursors like androstenedione? And, in your opinion, is it safe?


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?
