One of the reasons I tell kids in high school to get a vasectomy before they breed.
I hear you on knowing how to use a needle and thread, along them lines I keep a sewing kit in all my vehicles, some dental floss with a larger needle in it makes an easy to use setup that has some premo thread in it.

that is another thing you should look up if you take daily meds like I do for natural replacements, of course watching your diet intake of all the junk will drop off significantly if things go bad.
