I’ve noticed over the past year or so that when I get hard my penis has started to curve upward. Not too much but it didn’t do it before. I really started to see it around 15-16, the same time i noticed my penis getting larger. I am sexually active and girls have commented about my penis and the curve. Is this normal? Is it a growth spurt thing?
I don’t think it’s that unusual. I’m the same way, don’t remember when it started though. 
I think its fine I have a curve
