Legs just gave us the anwer.
Nature has given most females the wish for children in some point of their lives.
So they need a steady participant, hence getting married. Not incidentally a lot of marriages end up in divorce after 4-5 years because this is what it takes for the kids to grow through their most critical phase of life and a lot of attention/investment from both parents is needed. After that School takes a lot of care of the children so that the female is no longer tied up and may do things like:
- get a job again
- look for another horny stud with better qualifications
