1. Taking Panadol/Painkiller after s-x
It’s supposed to be as simple as ABC, ingest painkillers after having s-x. What is the worst thing that might happen, probably ingest enough to overdose yourself and actually fall sick.
2. Coca cola
Yes, apparently the Coca cola drink not only quenches the normal thirst but also does kill sperms, according to online myths. A woman is required to douche after intercourse, the carbon in the soda is supposed to be effective in preventing pregnancy. Women are still using this method to date. I think this is a perfect recipe for a yeast infection.
