Thank you for waiting and I understand the situation is very scary:

HEre are the studies regarding your risk:

The most widely cited study of per-act anal-transmission risk was published in 1999. It found that amongst men in high-income countries, unprotected anal intercourse with an HIV-positive insertive partner carried an estimated 0.82% risk of infection for the receptive partner per sexual act, or a 1-in-122 risk of transmission.5 It estimated the risk for the insertive partner as 0.06% per sexual act, or a 1-in-1666 risk of transmission.5

A more recent study amongst men from Sydney, Australia,6 has been able to more accurately estimate the per-act risks based on a wider variety of factors. The data support a recent meta-analysis of all previous studies of the per-act risk of receptive anal intercourse to ejaculation for both heterosexuals and sex between men, which was estimated to be 1.4%.7 Table 5.2 below, provides an overview of the Australian study's estimates.

Thank you for waiting, another expert was apparently in this question. There are clinics where you can go and get confidential testing done and get started on phorphylaxis as soon as possible since the risk is too high. Hopefully with him taking medications there is very little virus to be exposed to but the risk is still there and you should go NOW, the medications are a lot less effective as every hour passes.
