Interesting Facts
Birth Control
For as long as people have been engaging in sex they've been inventing unique means of preventing its frequent result: pregnancy. The most commonly used form of birth control over thousands of years has been good old fashioned "coitus interruptus" or pulling out before the explosion, but there have been many other most interesting approaches.
The precursors of modern birth control emerged in Egypt about 300 B.C. There they used mechanical and chemical methods that foreshadow modern diaphragms, cervical caps and spermicides. Their versions included lint pads soaked in honey and acacia tips, and crocodile dung compacted with auyt-gum, both to be inserted into the vagina as a barrier to semen.
Some Romans of the 4th century decided that the best way to prevent unwanted pregnancy was to diminish a wife's desire for sexual intercourse. Specific methods included: mouse dung liniment; swallowing pigeon droppings mixed with oil and wine; or rubbing her loins with the blood of ticks off a wild black bull.
Condoms began to come into their own during the eighteenth century. They were usually made of sheep gut, or sometimes fish skin and were originally introduced not for prevention of pregnancy but as a protection against syphilis.

In the 1600's Christians who lived in Turkey had to pay a tax. Tax collectors often required people to show their circumcision in order to determine who was taxable.

Female ejaculation
If a woman wants to learn how to ejaculate, she must first learn about the relevant body parts and how they function. Taking a look at the female ejaculation anatomy will increase your understanding of what ejaculation is, allowing you to use this knowledge to improve your sexual enjoyment and ejaculate ability. Ejaculation in men and women is the physical release of fluid from the urethra during intense sexual arousal or orgasm. The ejaculate fluid is believed to be produced by the Skene's gland, which is the female equivalent of the male prostate, where men's ejaculate is produced. The source, content, and amount of each component in female ejaculate is not entirely certain; all require more scientific studies and research to determine and confirm results. Some early assumptions suggested the ejaculate might be urine, however there are countless female ejaculators who report the fluid is tasteless and odorless, unlike their urine. In fact, it is not possible to urinate during extreme arousal, since the urinary tract is blocked prior to orgasm. Dr. Ernest Grafenberg, known for his studies of the female urethra role in orgasm and discovering the erotic zone later named the G Spot, also reported that an ejaculate from the urethra was definitely not urine. The G Spot is best located by inserting two fingers, palm side up, and pulling them back towards the palm or simply bending them. The area that the fingertips touch is the G Spot. This area has a rough texture unlike the surrounding vaginal walls. During strong sexual arousal, the G Spot becomes engorged, raising the flesh into numerous fluid-filled bumps. After ejaculation, these bumps diminish and return to the original rough surface. The G Spot is the primary area and function that you need to understand. Use this information as the basis for achieving a strong sexual climax and ejaculate.

Perhaps this G Spot orgasm is one reason why some women prefer to be on top for a more intense orgasm. It gives them control over how, where, and how much the penis stimulates the G Spot. With the G Spot more engorged, these numerous fleshy fluid-filled bumps would also create more stimulation to the penis, and a greater orgasm for him I would assume.

Maintaining Ideal Body Weight
There are 3500 calories in a pound of fat. For every 3500 calories you burn (that you do not replace with food!) you will lose one pound of fat. Sexual intercourse burns approximately 150 calories per half hour. Here's how that stacks up against some other activities that may be part of your fitness regime: yoga 114 calories per half hour, dancing - rock 129, walking - 3 mph 153, weight training 153, canoeing - 2 mph 153, volleyball 174.
According to one survey reported by the Ottawa Citizen, Canadians on average have sex 7.33 times per month, lasting approximately 24.4 minutes. That means that "Joe Canada" is burning off more than ten thousand calories a year, or about 3 pounds, in a not particularly active sex life. Those who are more sexually active, into Tantra for instance where lovemaking lasts 4 hours, would burn up 600 calories a session. At once a week that's 31,200 calories or 9 pounds per year. Considering that people put weight on gradually, slowly gaining 5-10 pounds per year until they are overweight, it's not unrealistic to assume that regular sexual activity is one way to help maintain a healthy body weight.

Sex as Pain Reliever
Through the touch magic of sex the hormone oxytocin is secreted in your body which in turn causes the release of endorphins. Because of these natural opiates sex acts as a powerful analgesic, elevating the pain threshold and helping to relieve the aches of conditions like arthritis, whiplash, and headaches. Now there's a novel approach, sex as a remedy for headache rather than an excuse for abstaining!
With arousal and orgasm oxytocin levels rise. They spike 3 to 5 times higher than usual just before orgasm. In fact it is oxytocin that triggers the orgasm. Measurements performed at the Masters and Johnson laboratories have shown that the uterine contractions brought about by orgasm (triggered by oxytocin) are just as powerful as those of child labor. Women can use this extraordinary orgasmic contraction and relaxation of the uterine muscle to relieve cramps during PMS and menstruation.
