Phimosis and STD Risks: Your Questions Answered - Urology

Phimosis, excessive pre-ejaculatory fluid, oral sex without a condom for one minute followed by wiping with a wet tissue, risk of HIV?

---

Hello, Doctor.
I have phimosis, and after retracting the foreskin, about one-fifth of the glans is exposed.
I previously asked about the issue of unprotected oral sex for about a minute followed by wiping with a wet tissue, but I realized I forgot to add some details.
Here is my previous question: "The second time I had intercourse with a sex worker was on April 7th of this year (last Saturday).
During oral sex, there was unprotected contact for less than a minute, after which I immediately wiped clean with a wet tissue (the state of my foreskin only exposed a little bit of the glans, approximately one-seventh to one-sixth of the glans).
I then immediately used a condom for oral sex, followed by condom-protected vaginal intercourse.
During this time, there was kissing (only lip-to-lip contact), and finally, after the partner helped me with manual stimulation while wearing a condom, I ejaculated." Before the oral sex, I had a significant amount of bulbourethral gland secretion (it was more than usual, forming a small transparent colorless ball; I compared it with pictures and believe it was bulbourethral gland fluid).
I read on Wikipedia that "studies have shown that the human immunodeficiency virus (HIV) is present in the bulbourethral gland secretions of most infected individuals, and infection with HIV can lead to acquired immunodeficiency syndrome (AIDS)."
1.
Is this true?
2.
Does this mean that having more secretion increases the risk of sexually transmitted infections (STIs) or HIV?
3.
Recently, I have been worried about STIs and have been retracting my foreskin to the coronal sulcus (I have phimosis, so it is somewhat difficult to retract, and I can say it is forcibly retracted).
For the past two days, I have felt discomfort and slight itching when wearing underwear, possibly due to the seams of the underwear.
Could this be caused by the hot weather and wearing tight pants for too long (at least six hours), or is it due to my anxiety about STIs making me overly sensitive? Or could it be related to using a small amount of soap while washing my genitals and groin recently? When referring to genital itching, does it mean feeling itchy when not wearing underwear?
4.
After the second sexual encounter with the sex worker, I felt very regretful and worried about contracting STIs, which caused me to be anxious and unable to sleep well.
For the next two to three days, I experienced loss of appetite, poor sleep, weakness in my limbs, swelling and pain in my right calf, and trembling fingertips when my palms were flat.
However, after reading an article from the Red Ribbon Foundation, I thought, "If I really contracted something, I would have to accept it; life must go on, and the testing date is not yet due, so there is no need to worry too much." This thought eased my mind significantly, and the weakness in my limbs, swelling and pain in my right calf, trembling fingertips, sleep issues, and loss of appetite improved a lot.
Doctor, is this anxiety about contracting STIs causing my symptoms, or could they be early symptoms of certain STIs or HIV (though I think the incubation period hasn't passed yet, so it shouldn't be)? I apologize for asking so many questions, but I would appreciate your responses to each one, as I am really worried.
