I quote this from a book.
'In many species, female mate with more than one male during breeding season, so 'sperm competition' is an important factor in determining which male is successful in fertilizing her egg. Seen from this perspective, males do not compete for females, but rather they compete for fertilizations. As a result of this competition, males have evolved larger penises and larger testicles, larger ejaculates and faster swimming size'.
Obviously we differ from animals in terms of competing for fertilizations. But it shows that to stand out from the competition, male species have evolves penis size, testicles and ejaculates, similar to what we are doing.
Take this how you want, i just found it interesting and thought i'd share.
