Thanks for your detailed answer. I just want to point out that, how do we know that a 10-yo male definitely lack of the ability to consent to sex while a 18-yo male definitely has the ability to consent?
If a 10-yo hardly knows why their penis get erected, many 18-yo males might not know why either. Then, what gives all 18-yo males the right to consent to sex while the 10-yo males are completely deprived of it?
If a 10-yo male had sex with a woman but proved his ability to consent and good knowledge about sex, why should the sexual act be criminalized?
