Hi Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern. There are a number of conditions that could cause small red spots over penis as follow:- 1.Genital herpes- Genital herpes is most common, lesions resemble small pimples or blisters that eventually crust over and finally scab like a small cut. These lesions often appear within the first two weeks the virus is transmitted and can take between two to four weeks to heal. 2.Your symptoms could be a ringworm infection, which is a fungal infection. Ringworm causes either a red, circular skin rash inflamed around the edges 3.Genital warts, caused by the human papiloma virus can also be the cause of the red spots. 4.syphilis can also cause red spots on genitals All the conditions above can be transmitted through sexual contact, so until you figure out what you have, you should be extra careful about protecting your partner from direct contact with the lesions or from genital to genital contact. The best thing to do would be to visit a physician, and he would provide you with a specific diagnosis. Hope your query is solved Get well soon
