I've noticed whitish like pumps on both sides of my penis frenulum, is it serious?

Hi there, I've noticed whitish like pumps on both sides of my penis frenulum. I'm arab, so I only have sex with my wife, never had sex with anybody else, she also never had sex with anybody else. I use laptop alot, I sometimes put it on this area, can this be the reason? and does it look serious?
