Condoms provide 50% protection. But its like every single sex act results in an infection. Sometimes it takes repeated encounters. Kissing rarely spreads anything. The chances are like 1% or less. You have a better chance of getting cancer from polluted air you breath, the tap water you drink, the cell phone in your pocket or the GMOs in the food you eat. Seek professional help for your stress. Xanax does wonders!
