The pull-out method, also known as the rhythm method, is potentially the worst possible form of birth control. Men do not always know when ejaculatory fluid begins to seep out and even ahead of a perceptible orgasm, pre-ejaculate, which includes sperm, is released and is enough to get a woman pregnant. In fact, 1 in 5 couples who use this method as their only form of birth control over the course of a year will end up pregnant.

7. You can catch an STD from a toilet seat

While public restrooms are host to a number of germs, from those that cause the common cold to Hepatitis A and sexually transmitted diseases like gonorrhea, most organisms can only survive for a very short time and the toilet seat is a highly unlikely transmitter of disease. In addition, to catch an STD in a restroom, germs would have to make contact directly with your urethral or genital tract or enter through an open sore, which is possible but very rare.

8. Premature ejaculation only affects young men

Some men do find that premature ejaculation begins at the onset of sexual maturity but plenty of men also find it to be an issue later in life. In fact, premature ejaculation affects 30% of men at sometime in their life. Although premature ejaculation can affect men of all ages, it can often be treated by a specialized physician. Often, early ejaculation in men who are in their 30 ™s or older is a co-symptom of erectile dysfunction or fatigue, poor cardiovascular conditioning, depression, anxiety or neurologic symptoms. In older, mature men it can sometimes be secondary to prostatitis.

9. A headache is a good reason to avoid sex

While many women, and some men too, have feigned a headache to get out of sex, intercourse actually relieves minor aches and pains, including headaches. Oxytocin and other feel good endorphins released during orgasm are responsible for the pain relief.

10. Certain foods can put you in the mood

Named for the Greek goddess of sensuality and love, aphrodisiacs are said to put you in the mood. While oysters, dark chocolate, strawberries and tiger penis might make you feel l ™amour, there is no scientific evidence to support the validity of aphrodisiacs. While there is no science to foods and/or herbs causing arousal, a certain food can trigger an erotic memory or desire in your own mind, so in a sense, we all have our own aphrodisiacs.
