By Kristina Smith Assistant Dimensions Editor Using a Condom Abstinence is the most effective way to prevent pregnancy and prevent STDs. However, this is not the preferred option for most adults, and especially not on Valentine's Day.
Condoms are a second option.
Learn how to protect yourself and your partner by learning how to use a condom the right way. Use a new condom before each sex act. Squeeze the tip of the condom to remove excess air and prevent breakage. When the penis becomes erect, place the condom over the tip and roll it all the way down. After coming, withdraw the penis while it is still hard.
