Condoms come in all shapes, colors and sizes. If you go to your local pharmacy, you'll mostly find regular latex condoms, some lubricated, others non-lubricated and others with or without spermicide. For the maximum protection, use a latex condom in combination with a spermicide. For even more protection, use a contraceptive foam or jelly in addition to using a condom. It's may seem silly, but follow directions.
Most condoms fail as a result of human error.
Also, make sure you only use water-based lubricants, anything oil based, like Vaseline, will damage the integrity of the condom and result in possible breakage. If you go to a specialty store, lookout for those condoms intended only for use as a novelty item. Also, ask your pharmacist what he or she recommends. And if you do choose to become sexually active, it's important to see your doctor for an annual check-up. Just be sure this is the right time and the right guy to share something so special.
