Foreskin won't return to original position, but...

It might be paraphimosis. That is the opposite of phimosis(when the foreskin cannot be retracted). If it won't go away, go to a doc.

It's not paraphimosis, which is caused by a foreskin that is too tight. It is much more likely that yours is too short, except that I say there is no such thing as a foreskin too short.
Of course it will be hypersensitive at first, until you get used to the new sensation of constant exposure. We all go through that. It will pass.
Consider yourself lucky. Most of us would like to have a foreskin as short as yours, but we had to work at keeping ours retracted.
I pulled this message from another forum:

I guess (Asians) don't see (circumcision) as necessary.
For them it is normal that the glans will be uncovered
after puberty, so what's the fuss? And if it's not,
that's when they think about circumcision.
A close acquaintance of mine is south-east asian
by origin and he told me that he retracted his
foreskin just once - about age 12 - and that's where
it stayed ever since. To him that's just the natural
thing to do. Is it paraphimosis? I don't know and
never will - we're both married family men.

Note: My brother, cousin and I, and others we have met
or heard about later on, did the same thing. But some
of us think it would be better to start earlier, just
as soon as the foreskin is readily retractable.
Mothers, if for whatever reason you are going to delay
or avoid circumcision for your son, consider this cost-
less, painless and totally reversable alternative which
provides all of the same benefits.
Do him an important favor and help him get his foreskin
pulled back off the penis head at the earliest possible
age.

yeh, i'm kinda in the same boat. When I was 19, I made a sex-toy contraption out of my bed. Basically, I stuck my penis in-between the mattresses. I did this several times, but the last time I did it, it caused my foreskin to pull back all the way for the first time in my entire life.

I'm 29 years old now, and basically...whenever my penis is hard, my foreskin won't stay in place. I can move the foreskin up and down my head if needed, so I know I don't have paraphimosis . but, masturbation hasn't ever been as satisfying as it used to be. It seems I can't quite grip my penis the way I used to. So, yeh...idk man...it is a weird issue and it really sucks. Especially not being able to masturbate the way I used to for 10 years now......
