I want to use condoms with my partner, but I am allergic to latex. What other options do I have for safe sex?

A latex allergy is a potentially fatal condition. Use of, or contact with, latex condoms—as well as cervical caps and diaphragms—is contraindicated for men and women with such an allergy. Oral contraceptives, IUDs and Depo-Provera are methods that may be used by those that suffer from a latex allergy, but they do not protect against sexually transmitted infections.

Fortunately, there are a range of non-latex condoms that exist in the marketplace today. Some, however, do a better job than others. "Trojan Naturalamb" is a lamb intestine natural membrane type of condom. It is not generally as effective as latex condoms. Also, they do not protect the couple from HIV or from sexually transmitted infections.

"Avanti" and "Trojan Supra" are polyurethane condoms. The "Avanti" condom has many advantages over those made of latex: Avanti is at least twice as thin and strong as latex condoms. It is nonporous and non-permeable to all viruses, including HIV. It is safe for use with oil based lubricants and is hypoallergenic. This condom has been improved over the years and is now only available in a SuperThin style.

The "Trojan Supra" is made from a highly advanced formula called Microsheer. It is ultra-thin, soft and hypoallergenic. It has no taste or smell. The "Trojan Supra" can be used with oil based lubricants. It is practically invisible when placed on the erect penis. The "Trojan Supra" is only available with spermicide at this time.

The Reality female condom is another choice for couples affected by latex allergy. This is a soft plastic (polyurethane) sheathe that is placed in the vagina prior to intercourse. It contains a flexible inner ring at its closed end and is inserted far into the vagina to cover the cervix. The second flexible ring at the other end of the condom is placed externally against the labia. When used correctly and consistently, there appears to be a reduction in the risk of sexually transmitted infections, including HIV. The failure rate in the first year of use among couples who use the method perfectly is approximately five percent. Among typical users, the failure rate is about 21 percent.

These condoms (as well as latex ones) can be purchased from retail stores or can be ordered online at such sites as http://www.condomania.com. According to the site, the "Avanti" condoms cost $11.95 for six. The "Trojan Supra" is listed at $9.95 for six. And three female condoms cost $9.95.

Condoms, either latex or otherwise, are effective if used correctly: Among perfect users, failure rates are approximately three percent in one year. Among typical users, the failure rate is about 14 percent.
