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 bumps or spots over penis, here are some common causes 1.Genital herpes, a common sexually transmitted infection , can appear as sores or lesions on the genitals. Classic genital herpes 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 indicate a fungal infection such as ringworm infection. Ringworm causes either a red, circular skin rash inflamed around the edges 3.Genital warts, caused by the human papiloma virus, could also be the cause of the lumps. 4.syphilis can also cause lesions on the genitals All the conditions above can be transmitted through sexual contact, so until you figure out what you have, you may want to 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
