>>11315244oh, so you're trying to base your arguments in nature, blegh, how mundane
by your logic attraction towards bossom and bottocks also is irrational as heck as they aren't related to sexual reproduction they are merely correlated with fertility (not even causated by fertility)
by that induction any sexual act that isn't strictly derivative of pp goes into a vagina is irrational- what a boring boner killer you are
but see your argument falls apart when neither penis nor vagina are equipped with precise observational organs that would confirm "yes this is definitively a vagina I am in" or "yes this is definitively a penis in my vagina"- they merely have sensory organs that send the signal "this roughly seems like a vagina or a penis"
it's all about stimulation, reproduction isn't be all end all of living beans
if you have unreproductive sex that doesn't mean you'll always have unreproductive sex and it doesn't mean others won't have unreproductive sex
stuffing your bepis into mouth, inbetween tits, in somebody's rectum or between armpits/kneepits (or in your case being rubbed by the feet) just like rubbing phalic objects against clitoris aswell as stuffing them into the birth cannal such as tongue, finger(s), entire fists and sometimes feet aswell as to some extend for males having phallic objects stimulate the prostate isn't irrational- you're not doing it for reproduction you're doing it for pleassure
sex stopped being all about reproduction the moment mammals started deriving pleassure from it, it's more than 1+1=3, it's about happiness, it's about joy, it's about power and dominance
should by your logic infertile people be banned from having sex? should they be shamed for it? shoukd they be called irrational just because they don't stick to the conservative norm of "rational sex is for reproduce"?
