a point made very clear during Akeem's recollection as he had no idea he'd even had sex until his realisation decades later.
Actually, Akeem says he was 'offered ceremonial herbs'... how can it be an offer, he takes them, but without consent? He doesn't say he declined them. No, he might not know the outcome, but the woman also doesn't know he doesn't know what the herbs are for. She offered, he accepted. They had sex.
