when naked alone in the house (when evere possible!)i always get an erection is it just me or does it happen to others
It's normal to get errections over anything during teens. Even from just the exposure of your penis to air when being naked
That happens to me i love it...
Your question is: Is it normal for a sixteen year old to get an erection every time he is naked home alone?
Yes. Yes, it is. It's also normal to get them when you're not home alone, when you're not naked, when you're at dinner, at school, hugging a girl you really like, hugging a girl you don't really like, hugging your mom (although this is a very awkward situation to be in, and most likely/hopefully is just a coincidence and actually has nothing to do with you having the hots for your mom. That would be uber-creepy.)
What I'm trying to say is, Dudes get hard-ons for seemingly no reason all the time, for a long time.
