I don’t know who will find this information helpful but I wish I knew when I was young.

A woman is only fertile during about 5 days each lunar cycle. Unfortunately those days are the most fun but the other 24 are safer.

Testicles descend when it’s hot to cool down because heat kills sperm. If you buy a microscope, and dunk your sack in hot water for a few minutes each day, you can become temporarily sterile and verify it with the microscope.

Finally, there’s a point you can press just in front of your anus that suppresses ejaculation. Any one of those things by itself would be risky but all three and it would be nearly impossible to fertilize an egg.
