You're saying consent to sex is consent to carrying a full-term pregnancy?
Why is that the case? Because you say so?
Let's be consistent with your logic.
Consent to driving is consent to a car accident, therfore medical treatment to fix injuries is not allowed.
Eating is consent to being overweight, so treatment for diabetes is not allowed.
Smoking is consent to cancer, so cancer treatment is not allowed.
And so on ...
Sure, we all deal with risk. This is nothing new. You realize there is only one way to create a fetus. This should not be any surprise. If it is to you, please do not procreate.
