Dear Porn Perv?,
It sounds like someone used your computer. Do you have a brother? Some people do look at porn--curiosity is natural. But I hear you and I'm glad that on my computer, if I google BOO, it autofills with a K, not a B. Stumbling on porn can be very unsettling because it in no way reflects how real women are supposed to look or act. Any chance you can discuss this with a trusted teacher or aunt?
