small spots inside the penis foreskin

hi my age is 25 years i didnot have any sex with any one.
but only i do mastrubation some times

small spots inside the penis foreskin while i pull my foreskin down it is displaying like this

there is also some white rudder like form under the penis foreskin but i am able clean it every day

Then i also have some tiny pimples like on penis glands

But those are any serious i need to do any checkup with doctor

what you can see in the photos are completely normal for an adult male penis …

thank you for your help
