ok well this is what you do. send him an email from work telling him

"ok tonight we're gonna **** whether you want it or not"

then, bring a gun home and stick it to his forehead. reassure him that you were serious in the email. now, if he complies, great--but keep the gun handy. if he doesn't want to, that's great to, but i don't think a corpse would be able to make the decision.
