tried and true remedies that help prevent/treat STI's

[jamesbond007]

Im not at all encouraging protected sex, but can attest to these remedies may work well with first hand knowledge/experience if something happens like a condom breaks etc

Iodine
Excellent all-round antiseptic and anti-fungal, best is lugols iodine, but povidone iodine will do if nothing else available.

Fungal,candida outbreaks on penis
-Vicks vapour rub ( has many therapeutic oils and compounds like camphor, cedarwood oil, turpentine etc )
