I will never forget the California sex ed class I sat through when I was a teen.

It was just a few hours...primarily on how to sneak a condom onto a penis (ie dildo in class) with your tongue without the john noticing.

First, maybe you should be protecting your teens from prostitution by using that class time as an intervention and funneling your services to keeping them off the streets before they're 18.

Second, the john's going to know if they're suddenly wearing a condom. No one is that dumb. So, in addition to encouraging underage prostitution, you're also going to get an underage prostitute punched.
