“If I’m on the pill, and my boyfriend and I are STD / HIV free, can we have sex without a condom? Or would the pullout method be alright?”
The birth control pill will protect against an unintended pregnancy if taken as directed while latex condoms offer protection against STIs. If you are certain that you are in a monogamous relationship (meaning neither you or your partner are having sex with someone else) then you would not be exposed to a sexually transmitted infection.
Condoms offer added protection against pregnancy so if you are not great at remembering to take your pills, you may want to continue using a condom. Withdrawal, or the pull out method is not very reliable!
