Hello, I've noticed over the last two years when I get an erection I have lost 2 inches in my length. I'm 32 years old now and I have no idea why or what has caused this. Throughout my adult life I've always from time to time measured myself and was always usually around 7-7.5". Since I've noticed this change in my size the last couple years, I'm usually anywhere from 5-6". I've tried doing research, but it seems there is never a concise or agreed upon answer.
When I have an erection it doesn't seem like I am fully erect and it isn't fully hard. I've thought that it could be possibly have been caused by masturbating or maybe low testosterone (haven't had this checked). I just don't know, but I would really like to figure this out, because it doesn't make sense how I can lose that size. I haven't gained weight or any other thing like that. Is there anyone who may have a valid medical opinion or who can give me some advice on hopefully gaining back this loss, if it's possible...
Any help would be greatly appreciated!
