As said above abstinence is the only 100% effective way to prevent an STD. A condom used correctly every single time would be the most common, but nowhere near as effective as you would like. Knowing your partner and getting tested before engaging in any sexual acts is probably the next best thing.
If you get caught up in the heat of passion GET TESTED the worst thing is an untreated infection or disease. Most can be treated if you know about it. Also, many come without symptoms so the best route is to get tested.
DonĀ“t make sex is the most effective! LOLBut if you use a condom surely reduces the danger.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
