[/INST] Hello, I had gone through your question and understand your concern. Short answer: NO, it's not a ring worm. Detailed answer: Thank you for your question on Chat Doctor. Semen when ejaculated gets coagulated immediately. After sometimes it gets liquified and sticks to the skin when ejaculated on skin. When this gets Chat Doctor.  This is completely normal. Normally, semen does contains any ring worm. So don't worry. Ringworm infection will cause itchy patches, discharge. Ringworm infection spreads from infected person througChatDoctorb, shower, clothes etc. I hope I answered your question. You can con contact me at any time, if you have any further questions. </s>
