Growth?

[disassociation2016]

I'm not really worried to much about being bigger, but do you think being "hard" contributes to you getting bigger? I mean sometimes I wake up in the morning and it's sore as heck like it's been like that all night. I'm guessing its stretching something...

Well I ant an expert but it is in your family genes. You ether are or arnt big.

Being hard contributes nothing to your size

Your penis wouldn't have been erect all through the night because that's far too long for an erection to sustain. It's common to wake up with erections anyway and most guys get it from early puberty onwards. It could just be sore because you lay in an awkward position while sleeping.
Like Noobzilla said, being hard doesn't contribute anything to your size at all.
