Can my sperms be mature enough to impregnate, when i masturbate everyday?

Normal men, women, boys and girls masturbate (it's universal). It is not harmful, as the body goes through similar effects during regular sex with a partner (but too much of anything may become a problem). Masturbation does not cause acne or hair loss, make you weak, create heart problems, lower testosterone, affect virginity, change your weight, lower fertility or chances of starting a pregnancy.

yes

Yes. However you should look into other ways of amusing yourself, e.g. through a hobby. Get HPV vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines
