will not retracting your foreskin while a teenager cause your penis not to grow to its normal size?

Hey, I'm 18 and I'd like to ask if not retracting your foreskin while a teenager might cause to the penis not to grow to its normal size. For a year now, I pull it back from time to time normally, but the thing is once I do, the foreskin it's like it's gathered and there's no more penis to cover, so there's like more skin in length than penis, and the truth is my penis is small (not a micropenis, it's just smaller than the predicted average, especially when not erected). When I was little I had something like paraphimosis, it was cured, but then it hurt when I retracted the foreskin, so it made me not retract it again from like 10-11 years old to like 16-17, and it feels like the foreskin is keeping my penis like inside and when not erected it's like the glans and some of the rest of the penis, but in situations like after peeing it gets longer (not much). I'm really confused, and I don't think I had a hormone problem while a teenager cause everything else in my body is fine-grown up, and as I said I don't think I have a micropenis, but I also think some of my penis is just used to be stuck back inside me even when erected? I don't know, anyone with any idea of what could be wrong? Thanks in advance.
