Has your penis shrunk as you aged?

Question

This is a question for guys 55 or older or possibly women who live with older guys. 
I am 56 and have noticed over the past few months that my flaccid penis has been considerably smaller that’ll normal.
My erection is still around the same size but when flaccid it is much smaller that I ever remember. Google isn’t any help with this subject so I thought I’d ask on here since there is a wealth of experience and people are good at helping others out. 
Im going to speak to my GP about it on my next visit.

When will the haters stop on this app. 
This community although mainly populated by females is NOT exclusively for their use. When will you learn this?
Did you actually read the title of the group that I posted in?
“Men’s Talk: Sex & Relationships
This is a group for men to discuss sex and women.”
The app I am using is called Glow. When I signed up as I wanted to track my wife’s cycle. I signed in as a male, used my real name and have contributed to several groups here and I like to think I’ve made friends. 
I posted in a male group stating that the question was for specifically males over 55 and I get a frankly rude comment from someone who has no information about him or herself on their profile. 
I suggest that you read things properly BEFORE you start to attack innocent people. Would you verbally attack someone in the street?
If you would then I don’t think I’d like to know you. 
I have made this response after careful consideration. I do not use bad language in my daily life but my first response did include some. 
I have edited it to be more restrained. I’m sorry if my post upset you but please, in future, read at least he group title before going on the warpath. 
If anyone has some sensible comments to make regarding my question I’d live to hear from you.

Answer

I work in the healthcare field. I see a lot of flaccid penis. It's a trend I've noticed in most if not all of my older male patients. Usually between mid fifties and up, there's the occasional exception but I'd have to say it's pretty normal. I've been meaning to look into the why of it but yea, you're not alone.

Update. 
Spoke to my GP and she says it’s normal. 
I suggested weight might be a factor and she agreed.

Answer

I'm 35 and have noticed the same thing.  But I think it's weight related.  I've gained 70 pounds since high school and have gone through a couple diets where I've noticed a difference after losing weight.
