It can also prevent ineffective, outcast, or weaker specimens from mating. If a woman could be impregnated in very few seconds consistently then the number of teen or child pregnancies as well as pregnancies resulting from rape would all increase dramatically. Some similar evolutions occured in Wolves, the wolves genitals are stuck together after reproduction and if an outcast attempts to mate he will be trapped and ripped to shreds.

Actually there is afaik a biological reason: Take it with a grain of salt,though - It’s a long time since I attended these lectures. The repeated insertion increases the need for lubrication(which increases sperm transport after ejaculations) and making sure the vaginal canal is opened fully.
Again, it’s a long time ago I had that lecture and it might not be up-to-date,so someone please confirm this.
