Not adding lubricant won’t affect condom use for most people. In part, this is because condom manufacturers generally add lubricant to most condoms anyway. A small amount of lubricant on the condom can help sex to feel more comfortable and pleasurable, and may also help to reduce the risk of condom breakage.
As anal sex is considered a high risk sexual behavior for passing sexually transmissible infections (STI), you may want to use condoms during anal sex should you and your boyfriend ever decide to go from having a monogamous relationship to an open relationship.
Some couples value monogamy and commit to only have sex with each other. Other couples decide to have some degree of an open relationship, which may allow for one or both of them to have sex with other people.
When men masturbate, they sometimes accidentally squirt semen into their eye. And men and women who have male sex partners have often been in this situation, too, so it’s an issue that many people can sympathize or even empathize with.
