Nevertheless, they would have to resolve any personal questions of propriety as to the manner of acquiring the semen.
No, no euphie, that's NOT what they said. They obviously left it up to the individual conscience. But, of course. "personal questions of propriety," means they should figure out a way to extract semen which
1) doesn't involve masturbation (self abuse)
2) doesn't involve involved "oral copulation"
3) of course, didn't include the illicit viewing of pornography
That leaves the options wide, wide open.
