I was having sex w my girlfriend and we used coconut oil as a lubricant. For four days I ve been having a burning sensation in my penis and when I urinate. She got tested a few weeks ago for all std and all came back negative. She has been the only partner I have had in a few months. I have never had an issue like this. Was wondering if the coconut oil could of gotten in my urethra and caused this. Thank you.
