Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of acquiring HIV from protected vaginal intercourse. From the information given, this scenario is determined to be Low Risk (Evidence of transmission occurs through these activities when certain conditions are met).

The scenario mentioned above does theoretically meet the three components of the transmission equation. In order for HIV to be transmitted, there must be an activity that may result in exchange of bodily fluids or direct access to the bloodstream.

Although you mentioned that the condom did not slip or break, evidence of transmission has occurred during protected sex. You have made the appropriate choice by using a condom since consistent condom usage is one of the primary methods to protect against HIV transmission; however, HIV incidence is only reduced by 80% with the use of condoms during all acts of penetrative vaginal sex. [1] You are correct in saying that the reason why it does not completely reduce the transmission is due to improper use and potential breakage of the condom, but previous studies cannot verify those contributing factors and therefore this is left unknown. We can only base probabilities from evidence-based studies so even though the possibility is rare with properly used condoms, it is still considered a low risk activity.

Keep in mind that the possibility of transmission is still less than 1%. [2]

Recommendation: Refer to a health care provider for HIV testing, due to the Low Risk exposure described above.
