Hi, For The Past Couple Of Days My Japs Eye

Hi, for the past couple of days my japs eye has been sore and red. I havent had sex since August so surely it cant be an STI. I tested this spray the other day before masturbating that was supposed to make me last longer and it stung abit, the day after it became a little worse and looked as if i had a blister each side of the japs eye and after having a pee this morning its almost burning.
