Adding extra water-based lube helps increase comfort and decrease noise. They're not to be used together with male condoms. However, they're pricier than latex condoms. Lambskin condoms, in contrast, are the oldest on the market. They're made from the intestinal membrane of a lamb.
Small pores make lambskin condoms ineffective in protecting against viruses that cause STIs.
But they do protect against pregnancy, since the pores are too small for sperm to pass through. All three male condom types offer the same statistical effectiveness against pregnancy, which is your primary concern. Contraceptive Technology estimates that only 3 percent of couples who consistently and correctly use male condoms will experience failure in the first year of usage. Female condoms have a probability of pregnancy of 5 percent, which still makes them quite an effective method of birth control. All of these options offer similar protection against pregnancy.
