Hello, I Am A Maritime Worker And I Have Been

Hello, I am a maritime worker and I have been out to sea for 6_7 months at a time. I am married but my wife and I only have sex when I am home for a short time.
During my trip to the Philippines I had sex with a very beautiful woman in her early 60's, now I am on my way back to the west coast and I find that my genitals have swollen thick two about three inches in diameter, and the length has grown by two inches. I want to impress my wife of 25yrs of age with this.
I think she would like it , except my genitals hurt all the time and is very sensitive to the touch, as well as a yellow to a mild brown thick ooze from the tip. I don't know whether to show her my new manhood or go to the doctor. I was thinking of just putting some Neosporin on it and a condom. If my wife wants to have oral sex then I'll ask her to use mouth wash afterwards. My friend said that as long as she gargles it should be ok.
