It's true that Torres was not capable of giving consent in that state but that's not why the writers had Paris refuse.
The writers had Paris refuse because it's a TV show and thus must be held to our double standards where we pretend to be forward thinking and progressive while we're actually super-conservative and want all relationships to be 1950s-idyllic. Two people must not make love without being deeply in love and signing the appropriate liability waivers.
that's bullshit. i don't give a toss about your 1950's idyll, i just don't want a character raping another one.
