Help me with these growing up issues!?

Hello, I am Bob, 14 and going into high school as a freshman. I have two questions really, first one is somewhat relevant to health but going through puberty has got me wondering if my is an average size for a male like me. I am 5 foot 5 and 120lbs and have a 6 inch . I know that people change at different rates, but I am curious to know if this is average. Second question is regarding fertility. I recently had to undergo surgery as one of my testicles could fully descend and the other testicle descends and ascends frequently but usually stays down. Does this affect my fertility in any way as I know they need to be a a specific temperature to produce sperm. Thank you.
