Not a medical expert so please go see a medical professional if the problem persists.
From my own experience however I would say they look like lymphocele or potentially random small inflammations of the veins in the area due to rougher sex/masturbation or some other irritant/trigger, like sweat. I had a similar thing on my foreskin immediately below the glans that would sometimes look more swollen and other times would look as if it wasn’t there anymore - usually moisture under the foreskin during hot weather, exercise or after going for a swim would cause a “flare”.
I got circumcised in my early 20s (unrelated reason, but might have been one of the many things I didn’t like about having a foreskin) and it eventually went away as I imagine the swollen bits just dried out from permanent air exposure. The area of skin that used to be inflamed was lower than the circumcision scar, so I still have that as a foreskin remnant, but my circumcision is as tight as it could be while still accommodating an erection, so all my skin is fully exposed even when soft. This I believe reduced the risk for any further inflammation as the mucosal tissue essentially dried out and I also have nothing to trap sweat etc.
I see you are either uncut or have a loose/partial circumcision, which means that area might trap moisture - not sure how much coverage you have soft? Try keeping it as dry as possible for a week and see it it improves things. This means full retraction (can try using tight underwear, a tape and/or a cockring to keep the skin back), and drying it out every time you pee and shower. If all fails, I really do suggest seeing a doctor. They literally see dozens of dicks a day and won’t judge in any way.
