Any place where a lot of people gather can be a potential target, I don't think just avoiding movie theaters will save you. A lot of countries already have metal detectors outside movie theaters and will search your bag, better safe then sorry so I don't mind.
Could be herpes, you can catch it even with a condom and no visible sores. I would be very suspicious of a pimple showing up with itchiness after a session with an SP. A lot of times herpes or genital warts start out looking like a pimple I think. Definitely go see a doctor and see what they...
Yes, people are that stupid. Why do you think infomercials are so successful, and those Nigerian scams keep getting people to send them money. If you have enough money to market it you can sell anything as a supplement to stupid people.
