For those who feel they cannot tell past or current partners directly, one can ask a healthcare provider for help with “partner notification”, whereby they will call or email your past or present partner to let them know (confidentially) that they have been named as a partner of someone who has tested positive for an infection.
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.
