Advantages
Condoms are the only type of contraception that stops you getting or passing on HIV and STIs
Internal condoms are a good alternative to external (male) condoms, because:
they can be inserted up to eight hours before sex, so there are no interruptions in the heat of the moment
most external condoms are made of latex, which some people are sensitive to internalcondoms are hypoallergenic, so they don’t irritate the skin
some men prefer internal condoms as they are larger so they give the penis more breathing room and can make it easier to keep an erection
during vaginal sex, the inner ring can stimulate the tip of the penis, and the external ring can rub against the vulva and clitoris – this can feel great for both of you
an internal condom does not need an erection to stay in place, so your partner does not have to withdraw straight after ejaculation.
Disadvantages
You have to use them correctly every time you have sex. But this isn’t difficult once you know how!
