The large number of sperm produced is natures way of making sure at least one finishes the trip and hopefully impregnates the egg. They are motile so that they are able to finish the trip.
A woman is born with so many ova, or eggs, at the time of her birth. She does not produce any more eggs through her lifetime but instead, looses one or more each month through menstruation A woman cannot use them after menopause. The supply of sperm is endless. A man produces more sperm as necessary and can produce them until he dies.

No. You can't catch a STD from yourself.
Sperms are too tiny to tell whether any got inside you or not, or whether at any point of intercourse any got inside you or not. Whether he has pre-ejaculate on his penis after pulling out or not is not relevant. There is a tiny risk that some sperms got inside you and get you pregnant.
What you are asking is- Are there any side effects if i forcefully try to remove sperms from the penis? Removing sperms (semen is the liquid that contains sperms) from the penis is called masturbation. There are no side effects of doing this according to medical science though there is a widely prevailing myth (false belief) among very many that it is harmful and the list of harm cited is so varied that it can fill pages of a book.
No. There is always a danger of STD if either party is infected.
Yes. Most meat is humanely produced.
The real question is why was any art produced!
