""there is a species of worm where the male is 200,000x smaller than the female and he insemenates her by being inhaled through her nose.
there is a kind of squid where the male dislodges his penis and projects the whole thing into the side of the female and it becomes a part or her body.
in japanese macaques (monkeys) the males and females will fight to have sex with a particularly sultry female, and the females masturbate themselves with their tails.
oragutans make sex toys out of leaves and branches.
sand sharks have intrauterine cannibalism where one fetus will eat his brothers and sisters in utero.
spiders have one penis on each side of his mouth
marine iguanas masturbate themselves whenever a female passes by so that they are closer to ejaculation if they happen to get a chance to mate.
apparently they will notoriously knock each other off while mating so the quicker a male deposits his genetic material the more likely he is to fertilize the eggs and so they've evolved to masturbate.
one fly, called a midge, liquifies her mate's innards and sucks him dry while they mate-sex and a meal in one.""
so the next time that you find yourself despairing about sex and romance among us humans (and yes, it is grammatically correct to say 'us humans' in this sentence) just be glad that you're not a liquified male midge fly.
