Wanting a girlfriend at 14 isn't a confession, it's hormones...
Anyways, I guess I'll give two.
1) My dad bought me a 12 pack of cheap razors awhile ago. Every time I use them, they leave my skin feeling like it's in massive pain, specifically stinging and burning. It gets really severe, but I 'ignore' it and never mention because: a) All pain is temporary, it's no use worrying about something so small. b) They work better than any razor I've had before (which is a LOT).
2) When I was about, say, 12 or so, we got a laptop from my dad's friend who works with computers. I pretty much used it more than anyone else really. Anyways, I usually used it under my bed because it was cool (temperature wise) and peaceful under there. I mostly just watched movies on this one site my dad found, but on one specific day, I got curious from discussions from school (despite having been the summer at the time), and actually went ahead and looked up porn. It was a bit of a risk I'd say, being in the middle of the day, but I don't remember ever worrying about it. Anyways, I actually managed to get somewhere, when suddenly, my mom gets to my doorway, obviously suspicious (You actually CAN'T see what I'm doing from under my bed, due to the positioning and bed skirt). She tells me to hand over the laptop, so I X'ed everything out and turned it off beforehand, but still panicked and wouldn't give it up. My mom knew something was obviously up, so she called my dad and told him that after work he needs to check the laptop, obviously through its history. However, when he looked, he could find nothing related to it. Why? I was using Safe Mode. He asked me if it was a bad pop up that worried me, and I just went with that. I know they never figured it out, because a few months ago, my mom actually asked me if I was looking at info or whatever about transgender stuff and did not want to get caught with it.
EDIT:: I should mention that this was the first and last time I ever actually looked at porn, honestly.
