slight irritAtion near urethra

whats up guys. i noticed a red irritation near my urethra around the beginning of June. I've noticed it sometimes gets uncomfortable not itchy more sensitive in very humid or moist conditions. my urologist looked at it and dismissed it. i haven't changed any new underwear so i don't think its from my clothes. if anyone has any idea let me know. I've attached some photos. this was after a shower but if you look closely could see 

Hi Like you uro said looks normal but  it could be just a bit of a male YI your having, get some coconut oil massage that in for 2 weeks 3 to 4 times a day and see how that goes, coconut oil fights YI's. OK
