This argument doesn't make sense for several reasons. Firstly, no one has the right to use your body without your consent in the first place, even a child, so you have every right to act to stop them from continuing to use your body if you don't want them to, regardless of reason. Secondly, taking action to avoid unwanted consequences is literally a normal thing that you're supposed to do. If you accidentally left the stove on and started a fire, do you just accept the consequences of your actions and let your house burn down? No, of course not; you take action to stop further…  Read more unwanted consequences by extinguishing the fire or calling the fire department. Similarly, if you get pregnant and do not want to be pregnant, then you should take action to stop that by seeking the medical treatment to terminate the pregnancy. These are things that normal people are supposed to do: take action to stop unwanted consequences, whether they were your fault or not. It is completely delusional to insist that people should be obligated to allow bad things to happen to them, despite being perfectly able to stop it.
