Birth Control.

So in my human development class, we are talking about different birth control methods.
Today we covered the history of birth control, and we also talked about some old methods.
They are crazy.
Here are some of those methods:

1. Weasel Testicles
2. Diaphragm: made out of crocodile poo
3. Beaver Testicles, with alcohol
4. Mercury
5. Diaphragms made out of gold and silver
6. Animal Intestines
7. Diaphragms of Opium
8. Lemons
9. Blacksmith Water
10. Coca-cola douche
11. Wood block pessary (sounds painful. What happened if you got a splinter up there?)
12. An actual sea sponge


I don't know about you,
but if those were my options, I'd rather not have sex than have one of those. A lot of those sound painful, unsafe, or plain disgusting.

Thoughts?
