¿Qué son esos pequeños bultos en el eje de mi pene?

For context, these appeared about a month or so after having unprotected sex with my girlfriend for around 2-3 months prior. I am curious if this might be an STD? Although it seems weird it would take almost 4 months for symptoms to show. I masterbate daily as well might that have something to do with it? Pics attached below.
