I love sex and all, but if herpes were the only STD in the world, I still can't see how casual sex would be worth it. Find a flaw in the logic here please.

Stat dump: 15% of people in the US have Herpes. They are contagious about 15% of the time (shedding). Condoms are only 65% effective against it. This brings the chance of infection from a ONE TIME HOOKUP to 1.5%. If it's a long term friend with benefits, you’re definitely getting it while they’re contagious so that person is a 15% chance of getting it.

How is the casual lifestyle worth the risk in any way? If you get it, asymptomatic or not, you’re screwing over tons of other people and yourself.
