Um yes I have like blisters around the head of my penis and bad smell didn’t know if there was a type of treatment or something?

Infection? Herpes? "Blisters" of the penis sounds like herpes. If you are uncircumcised, and if redness or irritation plus odor, it may be nonspecific or yeast balanitis, maybe helped by retracting the foreskin and washing with soap and water a couple times a day. See a doctor ASAP: if herpes, the sooner the better for accurate diagnosis and effective treatment.
