Just go to the Doctor and act like you really don't know what it is. If it is actual STD they'll tell you.
Seek medical treatment IMMEDIATELY! Better to be safe then sorry. Good luck mate I hope its not an STD.
I would be going to see your local doctor. Sounds like you have herpes my friend. Sorry If I sound alarming.
I would head to the doctors ASAP. Definitely sounds like something is wrong. Not sure If It's an STD or what...
Wish you all the best mate.
its possible that it could be an ingrown hair..
Lol maybe you just need to shower a little bit more bro.
