An internal condom also sometimes called a female condomwhich has the brand name FC2, is a pouch you safe to pull out and reinsert sex
into your vagina. Internal condoms work the same way that condoms do, except that you wear one on the inside instead of sticking it on a penis. They keep sperm inside the condom and out of your vagina. You have to make sure to use condoms correctly, every time, no matter what, in order for them to be effective. But getting a prescription for the internal condom is probably the cheapest way to go—if you have insurance, you may be able to get it for free with a prescription.
