If a male has genital warts can he make them worse by masturbating? if he has present genital warts and decides to masturbate will that make them grow in number?

You can spread genital warts to other parts of your body. I recommend going to a men's sexual health clinic to get advice about treatment options.

Masturbation does not affect HPV

If you have warts, how did you get them? They can spread, since you contracted them. See a doctor for treatment now and stop worrying about masturbating and get treated.
