You have gone way overboard in analyzing, reanalyzing, and second guessing the pathology reports. The bottom line is that your genital area lesions were not warts and were not caused by HPV. You need to stop examining your genitals.
I haven't a clue what is causing your sore throat. It is not HPV and probably is entirely unrelated to the sexual exposure described.
Oral HPV happens but is not very common. I am unaware of data about transmission by drinking water and I am skeptical. When oral HPV happens, it mostly goes away without ever causing disease. Although rates of throat cancer caused by HPV of one type (HPV-16) indeed are rising, it remains very rare and not necessarily the result of sexuall acquried HPV infection. Here is a thread that summarizes the current understanding of oral HPV, cancer, etc:

You need to get off your laser-beam compulsions about this problem, which is not normal. You are wasting an incredible amount of energy on a trivial issue. Because I will not risk contributing to that mentality, I won't repond to any further comments. This thread is closed.
