Hello, You are suffering from redness and tenderness in the tip of the penis. You have not given any history of your sexual life and partners. However, redness and tenderness at the tip of the penis commonly occurs due to urethritis, chlamydia, gonorrhea, herpes (these are sexually contacted). Non specific urethritis may also be caused without being sexually transmitted. Other medical causes can be UTI, injury, sensitivity or allergy to certain chemical in lubricants or latex. You should take care of your hygiene, wear soft cotton clothes. If sexually active avoid sex for a couple of days. Do not go for multiple partners. For relief, you can apply ointment Neosporin on the area affected multiple times a day. Drink plenty of water of reduce discomfort. Get STD tests done to stay on the safer side, if positive you will be treated with a course of antibiotics / anti-virals.
