it just looks like it has water, im really close to popping it

if it looks like it has fluid in it u should avoid popping it it could be herpes etc

so what should i do, i feels like is growing little by little

go to a doctors ??

ive search for herpes and it looks like it comes with a couple of pimples together so i dont think is herpes

also when i got circumcised and had my penis wrap up for a couple of days it was kind of tight so as i keep peeing i had this bubbles of pee form and i think the doctor just pop them
and this kinda looks like it

it has gottem bigger and it just stiff and the liquid inside of it is transparent is looking like it wants me to pop it plz can some tell me if they had seen anything like this or any advice i cant go to a doctor right now because i just dont have the money.
