they work about the same as male condoms do. The advantage of a female condom is a male doesn't have to have a full erection to use them. Disadvantages are price and I'm told they make a squishy sound.
I've never seen them in any store where I live. Easy enough to find online. You can even find them on amazon :)

Yes, most major pharmacy chains carry them, as do online stores.
I don't know how well they work in comparison to a male condom, but it is barrier protection so I'm sure it does have some effectiveness.
Do you have a regular partner?
u can buy them in any pharmacy, they are little bit expensive than the ordinary men condoms.
