dude this is normal and you don't need worry about it
if it is painful then see a doctor but if it is not causing you any discomfort then it is not an issue
I don't want to be so bold as to question you about your sexual history, however if you are a virgin then one thing you might want to be wary of is that a non-retracting foreskin that doesnt hurt normally might hurt when you try to penetrate - or, you could get the situation where a particularly fiesty girl who is wanting to perform some or other act on you, grabs hold of it expecting it to "roll down" quickly when its not that supple
If this is teh case then still worry not, because you can make your foreskin more supple by stretching it yourself. I don't want mods deleting this thread for me being too graphic, suffice it to say you can google it (maybe google circumcision and you'll find alternative suggestions to the operation)
a bit of GENTLE experimenting with gradually rolling it back a little more will loosen that papa up over a period of months
if it is very tight and causing you pain then the doctor can refer you for a couple of operations, one of which would be circumcision
