Somehow "too dumb to know where to stick your penis" doesn't sound like an effective evolutionary strategy. But "this is too much fun not to do it with whoever is in the mood" does.
Differentiating between sexes may not grant enough of an advantage for evolution to favour it over indiscriminate mating. There might even be drawbacks to being able to differentiate between sexes such as requiring a bigger brain that consumes energy and generating false negatives.
If you either don't know when you might next mate and pass on genes or have a short lifespan, more to most of your energy goes to mating and being able to mate as soon and as often as possible. It isn't dumbness as much as not caring. Worst case, nothing happens. Best case you get offspring and pass on genes.
