I have erection 22 times in one day until 8 times in one day in about a week is that mean i have strong sexuality and i have to much sexuality lust ?

Good for you: This is fine for a young man. You can entertain yourself, or maybe find somebody special -- that'd be great but it would make your life more complicated. "lust" is a word that some ideologue uses to upset you about feeling normal. Talk with an older man with some common sense -- maybe even dad (!) and when you find a relationship -- choose only the best & love responsibly.
