Unlubricated Condoms
Unlubricated condoms, such as Trojan Greens, are simply male condoms without lubrication or spermacide. They are used exactly like regular condoms. SSIS recommends using an unlubricated condom when performing oral sex on a male so not to taste the lubricant or spermacide, although it is not harmful to do so. While it is effective to apply personal lubricant or spermacide to an unlubricated comdom, SSIS recommends using a condom with these products already applied.
An unlubricated male condom can be used as a substitute for a dental dam by cutting the tip of the condom off and cutting down one side of the condom. It should unroll to a rectangular piece of latex.
