My very first reaction here is that you seem to be very "dry" as this may cause the process of moving the foreskin back a little painful, and it also may explain the little cuts which is probably dry skin, and possibly caused by friction from masturbation.
Try to use plenty of lube for a few weeks when masturbating, and also use a skin lotion too. I am sure this will hep.
BUT after a week or o, if there is no improvement off to the doctor and sho him or her what a big boy you are.
