It points to Aisha when she was 6 or so.
Reason:
Quote:"O Allah's Apostle! We get female captives as our share of booty, and we are interested in their prices, what is your opinion about coitus interruptus?" The Prophet said, "Do you really do that? It is better for you not to do it. No soul that which Allah has destined to exist, but will surely come into existence.” (Bukhari 34:432)
It's quiet clear that allah's apostle was against coitus interruptus.
he certainly told his men they should ejaculate within the bodies of women
If he didn't practice coitus interruptus (it It is better for you not to do it) his semen would have been inside his wives who were old and big enough.
As he was thighing Aisha, his semen would have been on his clothes.
Sex inside his other wives, means the semen was inside them.
