@Enceee I don't really care if ur joking or not.
But basically, foreign body removal refers to the sperm that is released in the vagina during intercourse, so the sperm will be identified as a foreign body/substance and will remove it(obviously his Shin's dick(penis) won't get removed because it's like sticking his finger up Cecily's nose or mouth) and so it will basically be like a method of contraception, and in this case it is mostly similar to spermicide, in turn it means they can keep having sex(intercourse) as much times as they want without Cecily getting pregnant because the sperm doesn't fertilise the egg.
Well guys, that's your small lesson on contraception from
@UND34D_M4N76 (check out my youtube channel "UND34D M4N" with the deadpool pic).
If you would like another lesson, please request and it will be my pleasure.
PS: Still in Year 11 and I know a lot about contraception, more than most boys and GIRLS in my year, lol. Also, just to clarify I'm a Guy(Boy/Male)
