Sexually transmitted disease
It's no secret that the most likely way to get a sexually transmitted disease is from, yep, you guessed it, sex. Takes two (minimum) to play this game. The overwhelming majority of reported STDs are caused by an organism called the zygote, which within hours embeds itself inside of a woman's uterus and begins to draw nutrients from her body. The zygote soon becomes a foetus, which gestates (matures), to become a baby. And even, worse, sometimes TWO or THREE pop out! So make sure he wears a rubber when you're fucking. Better yet, since they occasionally break, have him wear two or three.
For thousands of years, pregnancy and population growth were superstitiously believed to be a result of storks, cabbages, divine intervention, natural disaster and lying down in fields of buckwheat. Ancient peoples just couldn't put two and two together, but with the result of intensive studies and modern double-blind trials, modern science has definitively confirmed what a few misunderstood visionaries had been arguing for centuries - that babies come from sex. This knowledge has resulted in a great deal of shame in catholic cultures. Even in modern Spain a sufferer of the disease is derogatorily referred to as "la embarazada"
Scientists disagree whether a baby is an infection, a benign tumor, a parasite, or a fucking punishment led by Chuck Norris for people that doesn't want to have sex with him, this single-celled organism rapidly attaches itself to the uterus, where it begins to draw nutrients from the body of the sufferer, and if not removed early on in the process, gestates and is expelled from the body 36 weeks after the initial contraction of the disease, often with considerable anguish for both the sufferer AND the baby. Symptoms include vomiting, diarrhea, irregular sex drive and distension of the abdomen. The disease is also one of the greatest sources of human poverty.
Porking, screwing, knocking 'er up, slapping the kielbasa in the bun, doin' it, huffin' an puffin', and vaginal penile penetration are the most common activities that lead to this terrible affliction. There are millions of new cases every day. If fact, they are orders of magnitude more likely to lead to gettin' knocked up than similar activities like fellatio, dry humping, mutual masturbation, muff diving, tongue kissing, or blowing pot smoke in your cat's ears. And don't believe that just because you've had it once, you've developed some kind of immunity. Au contraire mon père (ou mère), 43% of the suffers from this affliction have already had it previously and have obviously NOT learned their lesson.
Prevention - Men:
In addition to wearing condoms, a surgical procedure known as a vasectomy can also be performed, which involves minor discomfort. In rare cases can also lead to a man's balls swelling up like grapefuits for a week and require a run of antibiotics. Women who come down with the disease and suffer for months blow up like the fucking hindenburg and understandably have little sympathy for men's complaints. Abstinence is a means of avoiding babies should be avoided, as this means not having sex.
Prevention - Women:
Women are the direct sufferers of this illness, and though men may complain of their pocketbooks taking a hit, once again, their complaints are rather petty compared to the plight of millions of women screaming out their lungs in maternity wards, midwiferies and taxis on every corner of the planet. However, relief is easily within grasp. There are a variety of hormonal treatments and devices available which make the woman's body unreceptive to the zygote's lodging in their flesh, as well as surgical and toxological remedies for removal of the organism once it's attached. Abstinence should NOT be considered. A brief look at the chart on the right will show how ineffective this tactic has been in preventing the spread of this disease, aside from the fact that anstinence means not having sex.
Today, tomorrow, next year... The treatment will cost you approximately 20 years of your life, then the little beast will turn on you.
