I had oral from a girl three days later had the discharge and burning but three weeks later after a lot of anti biotics I only have a slight sting in the head and when that happens I squeeze a few times and a tiny amount of clear stringy fluid will appear
Degree understand your concerns went through your details. Suggest you not to worry much. Your penis was burning after a mouth job due to the rashes you had during that.  You cannot blame that incident alone, your hygiene is also questionable. Three days antibiotic treatment may not be enough. Take a five-day course under a competent physician. Why do you want to squeeze your penis? The liquid escaping on squeezing could well be semen mixed with urine. Do not take self-medication. Please consult a physician. Hope this answers your query. Available for further clarification. Good luck.
