Even making it slightly more difficult or less effective should have been enough. Penises got optimised! That's why they have a plunger on the end! XD
Well, no. We don't need our little toes either and they are actually going and our foreskins might be too now we have underwear. No need to cut either off tho.

But evolution isn't philosophy. There is much evidence that human foreskins grew longer and more complex than that of the other apes and there must have been some benefit to this even if there isn't one now (there might be).
-
Observation that human foreskins are pretty large doesn't mean they're pretty useful. They would be modified exactly *because* something about them is in the way.
-
Only stuff that gets in the way of reproduction [by killing the bearer of the gene, or making him unlikely to reproduce] gets changed by natural selection. Things that are fine the way they are remain static for the same reason.
-
Yes, I know. This is evolution 101. Although it only needs a slight advantage/disadvantage to make a difference over evolutionary time. The foreskin got bigger and more complex in humans. There must have been some reason for this.
-
Evolution is way too messy for small advantages to have much of an impact. Otherwise our spines wouldn't be such a fucking mess.
-
No, it's not. This is how we refine where variation exists and it does with foreskins. They're not like spines trying to cope with us standing up.
-
Then explain why our foreskins would adapt to small advantages over the long run, whereas our spines are still ill-adapted to bipedal stance.

I don't know about the little toe. Client of mine complains a lot about missing one of his.

Read a thing about this recently. They are getting smaller. Many people's don't bend any more. They seem to be on their way out.
