White patches on face are they indicate calcium deficiency and anything to do with masturbation?

No and No: People with or without calcium deficiency can get whitish patches on the face. People who do or do not masturbate, can get whitish patches on the face. So, there is generally no relationship. However, every person should be sure to get an adequate amount of dietary calcium.

Remember: There aren't a lot of cutaneous(skin) manifestations of calcium deficiency unless it's been going on for awhile. You can get dry, scaly skin, brittle nails, and coarse hair. So the white patches are likely unrelated to calcium issues. Masturbation rarely causes skin issues outside your genitals(if even that) unless you have an allergic reaction to the lubricant.
