Does anyone really NOT know what a condom is? Ok, just in case: for a much more detailed description of these fabulous contraceptive and safe sex devices have a look at the main wikipedia entry
http://en.wikipedia.org/wiki/Condoms Condoms are not *just* about contraception.
If you're trying to be safe in your kinky explorations, then condoms are one of the most important weapons in your armory. Not only do they protect against most sexually transmitted diseases transmitted by the penis, they can also be used for none standard insertables (such as dildos and vibrators)both to protect your health, and even to protect your Sex Toys.
Things you should know ...
If you are using lubricants (lubes) for instance when having anal sex be careful about the type of lube you use.
Latex can be degraded (damaged) by oil based lubricants. Keep lubricants like baby oil and many massage oils well away from condoms.
You can get water and silicon based lubes from many sex shops and BDSM shops which are safely used with condoms.
Different brands of Condoms have different safety ratings. If you're going to be participating in vigorous vaginal penetration, and/or anal penetration, try to use the safest brands.
Personally I would NOT reccommend Boots own brand condoms, or those unbranded flavoured ones you get from novelty shops.
