Rashes on Penis forehead. Should i do?

Hi, Iam 32 yrs old married and 2yrs back I had burning sensation while urinating so I consulted urologist he prescribed me some medicines after which I was ok for almost a year but suddenly again last year on July I was having same problem while urinating for 3/4days & on the fifth day I noticed that my left testicle has swollen with severe pain so I again consulted with an urologist and I got admitted at the hospital after the check-up in the report It mentioned I was suffering from inguinal hernia. The doctor pushed back the tissue due back while physical examination which was very painful and prescribed medication for a month with bed rest. After few weeks the swelling healed but now from past 2/3 weeks ago I had an sexual intercourse using condom but after that I had multiple small round type rashes in penis forehead and also. I consulted a general physician and he prescribed me a medicine and ointment to apply in it for 2times a day. but it's healing properly. what should I do?
