>> a condom isn't 100% protection. <<
That's an understatement! Condoms are designed for heterosexual contact. Said one AIDS activist in the 1980s: "Wearing a condom during anal intercourse is like using an umbrella in a hurricane."
When it says on a condom that it is 99% effective when used properly, people should know several things:
1. Condoms are only improperly used enough that people having regular sex while using condoms still have 50% as many babies as people who do not use condoms while having regular sex.
2. The effectivess measure refers only to sperm, which are thousands of times larger than an AIDS virus, degrade nearly instantly, and tend to remain in the most viscous part of the semen.
3. Condoms are designed for vaginal intercourse only.
4. Many lubricants, which are commonly used for anal sex, degrade many condoms.
5. Anal sex is vastly more likely to result in abrasins and epidermal tears which allow semen-to-blood contact, making condom failure during anal sex much more catastrophic than condom failure during vaginal sex.
Thank you for stating the stuff I was too "delicate" to mention, lol!
Those same lubricants used by heterosexuals have also contributed to some "surprises", lol.
