It seems to me that you need to regain your sensitivity. Here are my recommendations for you:
First and most important is stop masturbate by rubbing your penis with your dry hand, instead do it by moving your skin back and forth over the glans, if your skin is too tight and you can't do it this way use lube instead, but never rub your penis with your dry hand! It is unnatural and ruins your sensitivity.
Second, start to restore your foreskin. Foreskin is very important for your sensitivity. If you don't know what foreskin restoration is then google it.
Third, if you watch �naked people movies� you better stop, it ruins the sensitivity in your brain. Google your brain on �naked people movies�.
It doesn't matter what kind of
Fleshlight you have, you should enjoy it and feel the sensations all the way to the orgasm. As I said already, I have a smooth sleeve and it feels fantastic!
BTW: What kind of
Fleshlight do you have? Just curious.
