STDs are not likely causes of such symptoms. I can't say whether there might be some non STD problem. If the symptoms continue, see a health care provider.
Thanks a lot for the quick response. I feel relief right after. But i do have a quick final question. I have sex with my regular partner yesteday and i feel some pain in my penis before the penetration and when we are done i feel some pain after ejeculation and then pain on left side of penis when i pee (right after sex). Is there anything to concerned about?
Welcome to the STD forum.
As you might have seen in other threads, often the earliest lines of a question tell me enough that I make a preliminary response before reading the rest. In this case, "The exposure was completely protected with condom (oral and vaginal)" tells me that almost certainly you did not catch any STD. Unless you say something quite surprising as I read the rest, most likely this judgment will not change.
Now I have read the rest. Guess what?
No STD causes pimples in the pubic area. That's a very common place for folliculitis (hair follicle infection), which often can be quite prominent. That's what is suggested by "a real big red pimple that is hard and really painful on my pubic area and it goes away in 3-4 days"-- certainly not herpes or any other STD.
And your other symptoms don't suggest any STD either. There is no STD that cuases "sensitive testicle". As for "irritation feeling in the penis", I don't know exactly what you mean -- but wihtou discharge or painful urination, no STD is likely. And you can't catch a urethral STD through an intact condom.
Finally, you go on to write "...recently...some body ache and i think it may due to over stress or anxierty. Can this be a symptom of STD or [am I] just overreacting?" As I have said many times on this forum, whenever a person suggests that his or her own symptoms have a psychological or emotional origin, usually s/he is correct. I believe you are overreacting to trivial, meaningless symptoms out of guilt over your sexual indiscretion -- nothing more, certainly no STD.
Of course if you remain nervous despite this reassurance, it is fine with me if you want to visit your primary health care provider or your local health department STD clinic for examination and testing. But rest assured nothing will show up (or if it does, it will not be from your condom-protected sexual encounter).
I hope this helps. Best wishes-- HHH, MD
