It's always nice to see the calmer, unbiased heads prevail, Jimbo. ;)

Timing counts; when a woman orgasms, relative to when a male does,
determines whether an orgasm is "high sperm retention" or low retention.
(See the literature, for goodness sake: Baker and Bellis 1993. Anim.
Behav., 46: 887-909.)

Interestingly for your assertion, non-orgasmic copulations result in the
greatest flowback (sperm expulsion).

I've regretted requesting citations from you in the past,
but I just have to ask: Please post your refs refuting my above statements.
