Its being itching there in my genitals. I am observing it from past 3-4 days when I last had my protected intercourse with my partner. He used lubricant and from that time I am getting itchiness down there. On 13 july I went bathroom many times and discharge was like colour of facial tissues we use and was very mild. Is it a kind of infection or seasonal. My test is negative. please tell me as this is due to season or due to my undergarments which generally get wet due to sweat. What should I do?
