Absolutely they do happen by accident.
That's what accidental means.
Well no, they're not all intentional. A broken condom isn't intentional. A forgotten birth control pill isn't intentional. A botched vasectomy isn't intentional. Fertilization and implantation aren't intentional. Premature *********** isn't intentional. Being raped isn't intentional.
I think you're going a long way to avoid the simple solution that is abortion. I guess I understand why you would do so. But I don't think blaming people is the solution. People do all kinds of stupid things without caring for the consequences. And you're forgetting that we tried what you are saying already, it was called the 1950s, but people still got pregnant.
But see that is the kind of person who will never think of his actions. He will drive drunk, he will smoke, he will download free movies online, he will do whatever he can get away with. Some people only learn the hard way.
unless it's done under rape than it's could be accidental? But maybe not maybe it was the plan all along?
Being raped and get pregnant is an 'accident'. For pre marital sex it's not appropiate.
I tripped and fell inside her... and came hahaha
