Tiny itchy bumps post body to body msage

Visited a massage parlor two days ago and took an oil massage, towards the end, the lady did nude body to body massage where she rubbed her body and lower abdomen on my penis, there may be some rubbing of vagina too, there was some precum on my penis. Later on, she provided a hand job and cleaned the ejaculation with a tissue paper. There was no penetraitive sex and only body rubbing and cuddling. Following are my queries, 1. Is there any risk of contracting HIV 2. Got itching and tiny ghamori like bumps that disappear after some time from the next day. Are these primary symptoms of rashes in HIV or just allergic reaction to the massage oil/lotion. 3. Are these true symptoms or just appearing as he Googled the symptoms and happening because of anxiety. 4. Considering these symptoms, should he take the PEP medication, please advise as today is the last day of PEP window. 5. What tests and by when should be done to confirm.
