Effective compared to what? If you compare the use of condoms to absolutely no protection then, yes, you are more protected while using a condom correctly. But before we jump on this bandwagon, let’s look a little more deeply.
HIV, which we’re all familiar with, is only prevented at 86% by the correct application of a condom. Wow, a whole 86%! Would you bet your life on that? Add to that the fact that condoms can fail from breaking, incorrect use, improper manufacture, or being too old. So you have a reasonable chance of getting up to 86%. That’s our definition of effective?
How about other diseases? How about human papaloma virus (HPV). Ever hear of it? It causes 99% of all cases of cervical cancer, which is deadly. HPV has many strains so you can get HPV and not get cervical cancer, but I’m going to assume you’re sane and you still want to avoid it. Let’s see how condoms help here.
HPV is spread through skin contact. Condoms cover skin, but not all that much. Unless you’re using a full body condom, you’re not doing much to stop the spread of HPV. Did I mention HPV is the most common STD in the US?
Now let’s look at the competition. As I said right away, they’re effective compared to nothing. But I wouldn’t recommend risking it; trust me on this one. Compared to the Catholic alternative of chastity and abstinence condoms, well, suck.
86% at best compared to 100% is not my idea of “effective”.
