You are still avoiding the question.

Is it high risk or not?

Your link says it is.

Here's the conclusion.

"The investigators encouraged researchers to consider such cofactors in future infectivity estimates, and they advised public health officials and clinicians to emphasize that heterosexual sex can be a remarkably efficient way to transmit HIV."

So anal sex is higher risk.

But vaginal sex is still very high risk, being "remarkably efficient".

Don't you agree?
