Q: My husband went to Walgreens to pick up some condoms. He said he saw VCF there, which he hasn’t seen in a long time. I went to the website because I’ve actually never heard of this film. Nowhere did it have it’s efficacy against pregnancy. It did however say “no birth control is 100% accurate” lol. We’re married and fine if it happens that I get pregnant..and it seems it might be better since we don’t have to stop to put on a condom. Thoughts?
A: For those who do not know, VCF is Vaginal Contraceptive Film. It is a small, thin, transluscent square that a woman inserts inside of her vagina. After about 15 minutes the sheet melts and coats the cervix with spermicide. It’s kind of like those mint strips you put in your mouth to freshen your breath, but for your vag to keep you from getting pregnant. It is not effective against STIs, and may actually increase your risk, which I will get into later.
The efficacy rates for pregnancy prevention are about 74% for normal use, 94% for perfect use. When paired with condoms the efficacy rate gets up to about 97%. When I say normal use vs. perfect use what I mean is that people screw shit up and don’t always do it right. In general, the more often you use something the better you get at it. So that 74% tends to be for the first year that you use a new method and your efficacy goes up from there. When I say 94% for perfect use that means how effective it is if you use it the correct way every time
You say that it sounds like it might be better because you won’t have to stop to put on a condom. However, you still have to stop to put in the VCF and then wait 15 minutes to make sure it is effective. So unless you plan ahead you will still be stopping and possibly stopping and waiting. And you may not want to plan ahead in this case unless you’re absolutely positive that you’ll be having sex later and this is why …
Nonoxynol-9
VCF is made from Nonoxynol-9 which is a spermicide. It is a very effective spermicide as it immobilizes sperm on contact. However, in such a delicate ecosystem as the vagina you might imagine that there could be some issues. If you use Nonoxynol-9 sparingly there shouldn’t be much of an issue if you’re in a monogamous disease-free relationship unless you are prone to infection. However, the more often you use it the more your vagina is exposed to this harsh chemical. And the more it is exposed to it the more likely you are to actually get vaginal lesions. For people who are not in monogamous disease-free relationships, this means an increased likelihood of contracting an STI especially HIV and HPV.
Like I said, it’s relatively safe if you’re not using it often, which is why you shouldn’t use it unless you are 99.9% sure that you’re about to get it on.
But there’s also the issue of oral sex. Say you and your partner have been having a grand old time fucking away and you just feel this need to have his cock in your mouth. Well now his cock is probably covered in spermicide and will taste not so good and will quite possibly numb your mouth a bit. Or maybe he’s been finger fucking you and rubbing your clit and then he just has to taste you … same thing. Genitals don’t taste so good with nonoxynol-9 all over them and they’ll also make your lips go numb and possibly your tongue.
This is precisely why I said 15 minutes of waiting. Sure you can makeout and feel each other up, but finger fucking and oral sex may make things less pleasant.
Conclusion
So VCF is decent at preventing pregnancy, especially when combined with other birth control methods, but it should be used sparingly and you may not want to put your mouths anywhere near anything that’s been put in your vagina. It’s a great options for some, and not so great for others.
