Don't rely on a rubber to eliminate your chances... it is only a sensible precaution that reduces the risk. Always stick with chicks in a low risk lifestyle... non-drug, non-drunk, non-whore/slut, etc. Ideally, she will ask YOU, first, if you are disease-free and will tell YOU that you must wear a rubber. If she doesn't insist on it, don't boink her again.

BTW, rubbers DO break. Try to always have fresh ones. Buy from high turnover places like walmart, and don't carry one around in yor pocket or billfold more than a few days.

For oral sex, have the non-lubricated or better yet the flavored ones on hand. You can use saran wrap when you eat p*ssy. Works great. Call it kinky instead of protection.

Watch for cold sores or cuts or abrasions, too. These little micro-injuries increase your risk.
