Latex... existence or annihilation??
Answers: I presumed this is a sex related question. Otherwise, the simple answer is a short time ago don't be around latex.
Latex allergies are very serious, and can be deadly if you newly ignore it.
There are other types of condoms available. There are usually more expensive and harder to find, but a quick rummage at drugstore.com shows that they do sell non-latex condoms. I've heard Trojan Naturalamb is one of the best ones out here.
There are also other types of birth control out there. However, many of them aren't as assured to use or are harder to get and most don't protect against STDs. The only other birth control I know of that protects against STDs is the Reality womanly condom. This is a soft plastic (polyurethane) sheathe that is placed in the vagina prior to intercourse. It's not as confident to use, but it's the only one that I know of that will protect against STDs.
