Since you did not have sex, it is not an STD.
I have had similar symptoms before. My symptoms were burning/tingling in anus, thighs, scrotum, and penis. Sometimes overt pain in one side of my penis. My doctor attributed it to a non-STD infection. His hypothesis was that the infection affected the nerves in the area.
In your case, maybe your damaged them via dry humping or had an infection (the symptoms you mention do not sound like they came from an energy supplement). Adenovirus for example can infect your digestive or urinary systems and cause all sorts of havoc. It is typically associated with the common cold. You could also have prostatitis. OR you could be worrying so much about your penis that it is causing the pain to feel worse.
Go see a doctor. He will most likely do a prostate exam.
No, you can't get an std that way.
Since you are a virgin, I would suspect this is something else than an std, and you do need to get it checked out.
Coundlt it be fro humping so hard that i damage the ureathra from i dont kno my penis bending ? and the irritation from the friction? but the thing is why would it occur 3 days after? n not immediatly if it was friction or somthing ... im still a virgin ... can u get an infection from toilet water splashing up and hitting your anus or penis tip?
Oh - If this dry humping is the only thing you are concerned about, then you wouldn't have an std from that.
There is no risk with dry humping.
Wow - I don't know if that's side effects from the energy supplement, or what happened after, or an std, but you need to be checked out, and I would do it sooner rather than later.
