Melody, at what point do you think someone is sufficiently developed enough to make choices? How does one arbirarily set an age and say that everyone lower than that age cannot properly make choice? And, as you said yourself, it is the late twenties and early thirties where the brain is finally developed fully. Should we set that as the age of consent? If not, where is the reasoning? The people younger than that, according to you, cannot make judgements as well as they would if they met that age requirement.
Besides this, what about older people? As we all know, after the age of thirty, the body begins to degenerate, in body and mind. Muscles weaken, tendons loosen, bones become less dense. But besides this, the brain loses mass at a very heavy rate. Indeed, after a certain point, not even at a very high age, the brain mass of an adult would be expected to be equivalent to that of a fourteen year old, and the myelin sheaths, too, would have a lesser size.
Are we to say that these people cannot have sex either, for they cannot consent to it? Are we to use the same faulty logic applied to adolescents on the middle aged and elderly?
And Michel, my point was that if they are going to have sex, they should use a condom, or at least some form of contraceptive. I know perfectly well the dangers of STDs, the causes of them, and the methods of transmission. This is why if I ever have sex with an untested partner, I would use a condom. However, if a person is not going to use a condom, as I said, they should at least use another method of contraceptive, though most do not. I fail to see how I have "trapped myself".
