"Conducted over a period of four years, the research involved 600 men aged 23 to 54 who exclusively identify as heterosexual and enjoy penetrative vaginal sex with women. They were divided into two groups: one received oral sex on a daily basis from a team of experienced homosexual men, while the other did not. At the end of the study, all 600 were screened for prostate and testicular cancer. Eight tested positive for prostate cancer; six for testicular. All fourteen were from the group that did not get serviced orally by gay men."
