I'm a straight male who only has had female sex partners. A month ago I experiemented with a male, we performed unprotected oral sex on each other. That's all.
About a week ago or longer I discovered a sore in my right nostril. It was a patch of a few small bumps that were white. They stopped huring after I put neosporin on them and they have appeared to shrink, but they're still there. For the past few days I've been experiencing a sort of pulsing sensation on my bottom lip, along with an itching sensation on my lips. (They're dry and chapped, lip balm helped) And I just discovered something that looks like a pimple just below my bottom lip.
Does this sound like herpes or any STD?
