We are totally not interested in discussing with you whether you have "phimosis" or not!
Because that line of discussion is going to get you nowhere and fast. That's why I warn you to ignore purported "information" on other sites about "phimosis" and "Frænulum Breve" and stick to the reading back through the site here - deeply.
The pictures you reference most likely do not illustrate a tight foreskin. As a matter of fact, none of them look particularly erect to me anyway but even allowing for that it is quite normal even for a foreskin that will retract, for it not to do so when you have an erection, until you actually deliberately slip the skin back. This allows for the fact that the foreskin, especially at the tip in a part called the "ridged band", is very elastic and able to both close down snugly or be pulled wide open as it goes back over the penis head. It in fact contains a form of muscle to do this. So pictures don't really tell you much unless a series of them show the foreskin sequentially in the process of pulling back.
Technically, you have "phimosis" but we can forget that, we'll just refer to it more correctly as a "tight foreskin" - what you need to do is to stretch it.
You see the concept of "phimosis" covers two things. As should be obvious to you now, when guys are born, the foreskin cannot be pulled back and certainly should not be. (There are of course, anomalous exceptions to this where the foreskin can be retracted quite easily or even is missing.) It is generally able to be pulled back some time in childhood or early puberty and indeed it might be expected that the young fella would discover this whilst playing around with it. It no doubt helps if he has someone else to observe doing this and want to copy, or at least parents tell him that this is what will happen - it seems you missed out on this education.
So people - notably doctors - are inclined to call this "phimosis". Well, there is a second situation where the foreskin at some stage was at some stage able to be pulled back, but starts to get tighter and progresses to the extent that it cannot be pulled back any longer. A medical term for this is "secondary phimosis", which means that the problem is secondary to some form of skin disease affecting the foreskin in particular. We discuss this here and the usual causes for it - and of course how to deal with it.
But what you have, is the first - you simply have not developed to the point of your foreskin being able to retract. At fourteen, it is now less likely to sort itself out on its own, so it will need a little help and you should get to work on the exercises (including the one to stretch the frænulum). There's no need to get down-hearted about it, you will have to give it time but - there is never any hurry to it. Just do the exercises and it will improve over time, eventually you will be able to retract, firstly when flaccid and later when erect.
