I only keep the ones that are really good so right now my porn folder is only at 26.6GB. It's just hard to sort through all the garbage if you have too many files. 

Most probably yes and many, many times.

I was almost 11 years old and it happened inside a classroom with at least 3 people whom I suspect knew about it.
The first one was my science teacher, the one solely responsible for my activities. He is smart, musclebound, and his dick always protrudes against his visible t-back so I couldn't help but get aroused whenever he was around. I always sat in the right corner in front of the room to get a better angle. While lecturing he would walk to the right and stretch his arms and cough a bit but he kept his distance. One time he asked me to eat lunch with him and I declined. Who knows what doors would have opened if I said yes.

The second one was my seat mate. Whenever I masturbated, I had a bag blocked against our chairs so I wouldn't be seen caught. At that time I was sure no one knew about it but growing up, I remembered he would lean considerably to his right whenever I did it. Finally, he accidentally hit my bag as he stretched sideways and my bag almost dropped to the floor but thanks to my reflex my left thigh caught it. He is now a cop and today my radar tells me he is not straight. I may have played a part.

The third one is the guy next to my seat mate.

We have never talked about this to this day.
