Cyst on penis?

Hi,

I have had this mark/bump on my penis for quite a while now, at least a year. Since I first noticed it, it really hasn’t changed. A doctor has looked at it before, swabbed it and said it didn’t look like an std and nothing came back from the swabs. Do you think this is a cyst? I plan on going to doctor but have to wait for meet and greet appointment then book follow up (family doctor recently retired).

Any opinions are appreciated!

can I see more of it?
