No, it does not hurt. There is a strange sensation which is enjoyable. The more often the boy masturbates the more enjoyable the ejaculation of semen becomes.

No semen used for your cows is artificial. It comes from a bull (since it is produced naturally by a bull), stored in semen straws and shipped to your farm to breed your cows with. The length of time it takes for semen to arrive depends on how far away the company you ordered it from is or where you're getting it from. The AI company you ordered the semen from would have a better answer to this question than anyone on this site ever could give you.
Not at all, but they are slightly annoying at first
Semen is made new after every time you cum. If you really have problems and nothing comes out you should go see a doctor. If you are a teen boy who haven't come that far into the puberty though it can come later.
