People post funny things here all the time. Here's one I came up with to discourage my sister from sex when she was 16. My math may be slightly off. Enjoy!
Whenever a man ejaculates, he releases, let's say, 300,000,000 sperm (million, people!).
If you have sex 3 times a week, that's 9 hundred million sperm.
If you have sex 3 times a week for a month, that's 27 BILLION SPERM!
and it only takes one ladies...
