if you masterbate to much does the skin inside come out ?
You mean the skin that covers the glans (head)? Yes, it could swell from if being irritated. Swelling may happen with urethra opening too, if you had that "tip" on mind.
It's all normal, don't worry.
ok thanks so much it is just one of those thing what get stuck in your mind.
No. Masturbation is relaxing, pleasant, harmless, healthy, and contributes to restful sleep if done before bedtime.
How you do it depends on whether you have an internally lubricated foreskin that glides up and down the shaft or whether you have been unforeskinned.
If you are foreskinned, then all you need to do is slide your foreskin back and forth. The internally lubricated foreskin glides without friction.
If you are unforeskinned, then you will need some lubrication and you need to slide your hand up and down the shaft. You will likely injure yourself without lubricant. Some lubricants are baby oil, vegetable oil, personal lubricant, soapy water, and saliva.
It is common, however, for an unforeskinned male, who has been deprived of his internally lubricated foreskin, to have friction burns if he does not apply external lubricant.
