This is very interesting finding and I have suspected that most cancers have a viral etiology.
My master's thesis did not find an association between increased number of sexual partners and prostate cancer when looked directly, but did find a highly significant association and interaction between high number of lifetime sexual partners (10+) and men who had a first degree relative with prostate cancer.
Unfortunately, due to political reasons, I was not permitted to publish this finding (just used it as my master's thesis).
Since the majority of people are exposed to these viruses (HPV etc), the rate limiting factor for how soon a man develops prostate cancer may be his personal genetic makeup.
