Thanks for posting your query to HCM.
With so many of information provided I can get that you want to have sex without condom. If you are confident enough that both of you are not having any sort of STD's and both of you are totally committed to each other then you can very well be in love without condoms. there is no effect of any medications in preventing or increasing the STD directly. But your partner should take the pills regularly to avoid pregnancy
Go ahead have wonderful life.
