It is possible that you have balanitis. You should get this diagnosed by a doctor since it is impossible for a doctor on this site to give a proper diagnosis without being able to see you in person.
All the best.

It's kind of hard to say what it is. There's no swelling or redness around the white spots. Have you changed condom brands, your soap or laundry detergent lately? The best thing to do is see your Dr. I wish I could be of more help. Remar
