@1234567890 Hi and welcome to A2A. If your foreskin is loose enough, just use your hand to slide it back. If it is still tight, which is very common, you will need to do some stretching exercises to stretch the skin. You will find lots of discussion about this in the "Foreskin and Circumcision" forum. If you decide that you need to do the stretching exercises, the key is to go slow and not try to stretch too quickly.
The foreskin will retract somewhat on it's own when you have an erection because the penis shaft grows in length, but the foreskin does not.
When you are able to retract the foreskin, you will probably notice some heightened sensations when masturbating because your shaft has been covered and protected by the foreskin since birth.
The frequency of masturbation is different from guy to guy. Sometimes you feel horny and sometimes you don't. Twice a day should not be a problem as long as you don't create any abrasions on your penis.
