Exotic Condom Flavors

Condoms made from sheep intestines, labeled "lambskin", are also available, although they have been clinically shown not to necessarily keep out STDs compared to latex because of pores in the material, which are thought to be large enough to allow infectious agents to pass through; sperm is still blocked. Lambskin provides more sensation and are less allergenic than latex, but because of their comparatively less-safe nature, other hypoallergenic materials such as polyurethane are recommended for latex-allergic users and/or partners. Lambskin condoms are also significantly more expensive than other types, similar to polyurethane's comparative expense to latex.
Spermicidal
Some latex condoms are lubricated at the manufacturer with a small amount of a nonoxynol-9, a spermicidal chemical. According to Consumer Reports, condoms lubricated with spermicide have no additional benefit in preventing pregnancy, have a shorter shelf life, and may cause urinary-tract infections in women. In contrast, application of separately packaged spermicide is believed to increase the contraceptive efficacy of condoms.
