Dear Alice,
I was told that using two condoms causes excess friction that can actually break the condoms down structurally. Kind of like vaseline. Is this not true?
Sincerely,...

Dear Alice,
My boyfriend recently suggested that we use two condoms at once while having sex because it would decrease my chances of becoming pregnant. How reliable is this and why haven't I heard about this before? We've been using a single condom. Also, which is the best spermicide that can also act as a lubricant?
Sincerely,
Cautious
Dear Cautious,
Using two condoms at the same time is not recommended for either safer sex or pregnancy prevention. In fact, "double-bagging" can increase the friction between the condoms during intercourse, making them more likely to rip or tear.
It may be reassuring to know that, even on their own, single condoms are highly reliable in preventing not only pregnancies, but also sexually transmitted infections (STIs), when used consistently and correctly. Most condom failures result from human error, mistakes that people make, rather than defects in the condoms themselves.
Other effective ways to decrease the likelihood of a pregnancy include using a "back-up method" of contraception, such as a condom with a diaphragm, birth control pill, or another hormonal method, such as the contraceptive ring or patch.
As far as spermicides are concerned, using spermicidal lube is generally no longer recommended. Spermicides alone not only provide minimal pregnancy protection, but nonoxynol-9 (N-9), found in many spermicides, can cause irritation and possibly facilitate HIV transmission. Spermicidal lubes may be a safer option for couples who are monogamous and have little reason to be worried about HIV/STI transmission; for others, choosing a spermicide-free lube may be preferable. When choosing a lube, pick water-soluble, not oil-based, ones, to prevent deterioration of the latex in condoms.
If you are a Columbia student, Primary Care Medical Services (x4-2284) can directly answer any other questions about effective birth control options. Otherwise, any health care provider can be a resource.

Dear Alice,
I read your answer on using two condoms: "Some people try to add a couple of percentage points to these stats by wearing two condoms -- and yes, doing so might do just that, although Alice doesn't know of any scientific studies.
In every package of Durex condoms, they have "10 basic tips on good condom use", and number 3 says: (translated from dutch) "NEVER use two condoms at once. Due to the friction between the two condoms, they might tear or slip off."
So, according to them, it's not such a good idea...
Bye,
