help whats the bump on my penis shaft

I have this bump on my penis shaft and its painful when i touch it or rub it and I've got it 2 days ago after shaving then had sex but used protection and am not sure if its from shaving or the sex i had

if its painful it may just be a spot not uncommon to get spots on the penis

You reckon i should get it checked?

if it feels like a hard spot theres no need as it will just be a blocked pore like when u get a pimple if it dosnt go away within a week or gets worse and more appear get it checked out
