I had some issues with irritation and redness around the peg too. Naturally, I wanted to keep it as clean as possible and disinfected the heck out of it. (Bad idea) When I finally regained my senses I just scraped off the gunk that accumulated around it and washed it once in a while and the irritation and redness went away.
Christine, the port is also not a big deal but it does take longer to take it out (maybe 15 minutes).
