There seems to be some basic misunderstanding between the two of us on what consent *is*. Not on the definition, because I have no issue with the definitions you provided, but on how the definition is applied to practical cases.
I can consent by walking up to someone and saying "please do X".
My consent can be implied if I say "please to Y", and I know that in order to do Y, X needs to be done first.
It can also be implied if I say "please do Y", and either X or Z lead to Y, but X is more in line with my known interests.
In any case, my consent is linked to my intention. Consent is an intentional act, and implied consent needs to conserve that intentionality, either by reference to another intention I do actually have, or by reference to an intention I would presumably have formed, had I been aware of the options.
You might ask why intentionality needs to be conserved. My answer would be that by consenting, you waive rights. Since only you can waive your rights, this waiver needs to be attributable to you as a subject. And the way to do that is via your intentions.
If you disagree with this on a fundamental level, we need to have an entirely different discussion on the fundamentals of self, action, responsibility etc. before we can continue here.
Now, assuming you do not disagree that consent needs to be linked to intention:
If you do not intent to have a child, and do in fact hope or assume that the sex will not lead to pregnancy, then you do not consent, implicitly or otherwise, to the consequences of that pregnancy. To assume you implicitly consented by having sex would ignore your actual intentions and replace them with the opposite.
If, on the other hand, you do intent to get pregnant, or at least accept that result as an acceptable outcome, then you could be said to have implicitly consented to the consequences of that pregnancy.
So there is a case to be made on the basis of implied consent, but only for intentional pregnancies.
The reasoning here is that unpredictable or extremely unlikely outcomes of an act of free will are not actually expressions of that will.

because ...... yet again you need to support the reasons behind statements like that. Give an example of where it would apply. As it stands it is just an opinion - — Rank Amateur
I did not expect that statement to be controversial. You are familiar with the term "butterfly effect", I assume? I think it's fairly obvious that you cannot be responsible for every possible outcome of your actions. That would turn responsibility into mere causality.
As a matter of practicality, you cannot expect me to give you a full argument from first principles for every single statement I make. It'd take entire books worth of text. I would ask you, instead, to note when you have a fundamental disagreement. We can then try to establish the closest common ground and work from there.
but your wrote... — Rank Amateur
I avoided using the term responsibility in the bits you quoted on purpose, though I cannot fault you for not knowing that. I don't think financial burdens need to be based on responsibility. Society needs to distribute burdens somehow, and sometimes this means that a financial burden ends up with someone who is not strictly responsible for it's creation. I know this is not a full argument. If you are really interested we could discuss it at length as it's own topic.
I agree.
but in the what would be the right thing to do " give blood" - I vote yes. Give a kidney - I say no.
How about a 9 month blood transfusion - that only you can do, to save the life you put in danger ? — Rank Amateur
I think the fact that we feel the need to differentiate between a single blood transfusion, a long term transfusion and donation of a kidney already establishes that responsibility for the pregnancy is not sufficient to completely overcome any interest the mother has in her bodily autonomy.
I think the argument can be made that, regardless of morality, it can never be a legal obligation to provide your body to others. But this is just my opinion at this point, to establish it as an argument we'd have to talk about the difference of morality and legality and that is a thread in it's own right.
In the realm of morality, I think in order to progress at this stage, we'd need to establish just how much responsibility sex entails. I don't think having protected sex is negligent. Unprotected sex, maybe, but it's probably not "running a red light during rush hour" negligent.
