Could a red pimple on the thigh post-sex indicate early HIV?

Hello doctor,

I had sex with a sex worker a day before yesterday. But I told her not to remove her dress because I did not have a condom. Then I had a hug and allowed her to suck my penis for five minutes. While doing, she told me that my liquid is coming in her mouth, and so I stopped. After that, I sucked her breast some time. I do not know either milk is coming or not. Then finally I told her to do hands blow job after which I ejaculated.

My question is the next day I got a red pimple in my inner thigh on both sides and is getting irritated. Why is it coming suddenly? I feel it may be an indication of HIV. It happened only after the incident. I was thinking in two ways. Could it be due to my liquid which went inside her mouth, if she has an infection? Or maybe due to that, I have sucked her breast I felt I might have drunk her milk. Is this an initial infection of HIV? Kindly look at my attachment. Please advice.

Hi doctor,

Thank you for your reply.

I did not insert my penis to her vagina that is confirmed. But only what I did is, I sucked her breast and as same as she did my penis which I mentioned earlier.

1. Yesterday I had itching and pain while walking, and I applied Aloe vera natural leaf because of which itching was reduced.

2. Is this surely not symptoms of HIV?

Thank you.
