Can extending & jelqing cause Fordyce spots?

Hi guys. I just started extending and jelqing a month ago. I usually do 2 hours of extending followed by 100 reps of jelqing. Rest, repeat, 8 hours extending a day.

A couple of days ago, I noticed small white bumps of the shaft on my penis. It seems they are called Fordyce spots:

Basically, they are visible sebaceous glands. Could these be caused or exacerbated by extending and jelqing? I do not think I had these before. If I did, they were not as prominent.

Any tips, ideas, advice?

Thanks!

I’ve never heard that. Please, compare your bumps with the Fordyce spots in these pictures. Are they similar?
