<s>[INST] about a month ago i discovered a small red waxy mark on the head of my penis. it s not at all painful and there s no discharge or anything. i was wandering if this seems like an std, maybe herpes or syphilis? or does it sound like something else? also for the past few months I ve had small painless white spots in the corner of my lips, i saw a dermatologist about this when i first noticed them and he said it s nothing but now I m worried that the 2 may be linked. is this a possibilty? What do these symptoms suggest? ...
