I stepped on on glass in the park, i got a deep puncture wound for sure, I dont want to go to hospital?

I was walking bare footed, stepped on glass cut my foot, I then went home soaked it in alcohol then paraoxide, after soaking it I cleaned it with more alcohol and iodine. Is it really a nessessity to get medical attention. I dont want to but everyone is tellin me to, I have had staff infection and I healed that by myself and i feel I can clean this and keep it clean my self? what do you think?
