My penis glan is unusually wide and big than others that's why my foreskin comes behind the glans stuck behind it,and my glans became red. once my foreskin retracts, it stays back until i slip it forward again. so is there is any problem ?

For those uncircumcised, swelling and white discharge on the penis is cause by a yeast infection, called balanitis. Usually this can be alleviated with hygiene. This can also lead to another condition called phimosis, when the foreskin becomes unable to retract behind the glans. Paraphimosis is a urologic emergency, when the foreskin becomes trapped behind the corona of the glans penis

If you can bring it back forward easily then there is no problem It will get looser with time. Good luck
