Warning, incoming novel that includes things you don't want to read.But are kind of necessary to fixing this issue in my honest opinion.
(Noting of course, you may experience this because of natural body chemistry, I'm going off the assumption that this is not normal for YOU. Because you're here questioning it.)
I'm going to be "
That guy" and tell you to see an OB/GYN. (Most family doctors will tell you the moment you say "privates, plumbing, personal parts, down there, or NETHER REGION" to go see one anyway, so you might save yourself or your parents money by just directly requesting one. Note I don't know how old you are, so the yourself/parents thing is heavily depending on situation.)
It might be a bacterial infection (Which is VERY common in the original plumbing for us guys. Some are lucky enough to never deal with it, but literally /anything/ can throw it out of whack and become an ordeal.) which can result in bad smells, discharge, but it does NOT result in pain normally. Which is one of the big differences between bacterial issues, and fungal issues.
Now, for me? I had an issue like this years ago, where it got bad because I didn't see a doctor. I tried all the internet home remedies. I tried the vinegar, I tried the yogurt, I tried the aggressive soap scrubbing, everything. Didn't work.
Because vinegar, yogurt, and soap all have two things in common.
1. They screw up the plumbing's PH. Either making it too high, or too low. Which means it's balance is effected, it's GOOD protective bacteria is dying, and it has to work to fix that.
2. They contain bacteria. The wrong kinds of bacteria. Which only adds to the problem, or lessens it for a VERY short time before it becomes just as bad. Hell, these new bacteria might even kill the protective bacteria that are left, fighting these goddamn foreign invaders. It's like a staph infection on your skin.
Now the thing that fixed it?
I saw my Ob/Gyn, he asked what the problems were, I told him the exact symptoms, told him there were key things missing from a fungal episode, and he prescribed me an antibiotic (One which apparently is used especially for this issue.) and then within the week and a half it took to take the pills, everything was 100% in that plumbing, and it has been for years after.
As horrific as it sounds walking into a place where there's a bunch of ladies staring at you, trust me on the fact that you need to take care of yourself first. (I was shaking and horrified and just so upset because of my dysphoria. But the staff was very friendly, very supportive, and I was texting a friend through the whole ordeal and it really helped me.)
And if you're worried about how the office will treat you, call ahead, ask them their trans policies, ask if any of their doctors are experienced working with transmen, and pick an office from there. Many are becoming quite used to us guys, and as medical professionals do what they can to use our preferred pronouns and names. I hadn't picked out a name at the time, so they just used my birth one, but I did tell them that I preferred non-female terminology, and my doctor was happy to oblige. He also said a lot of ciswomen prefer not to hear it as well, so I imagine it's a common request!

And the staff was fantastic, just like my doctor; I told him I was /not/ comfortable with an examination at that time, for a multitude of reasons including the fact that I had bad gender dysphoria, so he nodded, asked a few more in depth questions to make sure he could go on the fact that without seeing it/testing it first hand it WAS that, sent me for a piss test, and then within 30 minutes when the result came back he prescribed my miracle cure, and that was it.
Please, for your sake try to give these doctors a chance. I know the dysphoria hurts, I know the reminder is depressing, but once it's all over with you wont have to think about it, because the fix will let you take all of these other fantastic guy's suggestions like the stick loofas, and such to heart so you can rest easy knowing that the hygiene is taken care of, and there wont be really any other problems for a while.
Also, one super important note.
Once you've fixed this problem
ONCE IT IS GONE.
Do NOT, under any circumstances put soap /inside/ this plumbing. When you wash, wash the skin outside, dear gods in the pantheon DO NOT PUT SOAP INSIDE. It will do what I said up there in this novel long post, and screw up the PH, killing the protective stuff and leaving you vulnerable to bad bacteria for a while.
Washing around the outside is fantastic, and keeps staph (Skin) bacteria from hurting that area. (Since you know...it's all dark and sweaty and gross down there.)
ANYWAY OK I'M DONE. Good luck, hope you get this fixed one way or another man. <3
Tai is outta here.
