Red dots appeared on penis head, peeling afterwards. Please help

Not sure if you can see the pictures, but on my penis head, these dots started appearing. Small red dots, would not be noticable if a third party glanced. While i was on vacation a girl performed oral sex on me, no condom. The morning right after i saw a lot of those same red dots but more noticable this time and very red. 3 days later when I came home a few went away and ive experienced a small amount of skin peeling where the dots remained. on day 5 now and it looks like this. No more red dots, just red patches where the skin peeled. Never any drop of pain, absolutley no itching unless i was touching it. no discharge, no discomfort. if it wasnt visable i would assume nothing was wrong.

please please advise if anyone knows anything at all as to what this could be and what i should do.

balanitis possibly

Hi
They might be allergy reaction or thrush or rash or mild herpes
I will advise to get IGG blood test for HSV 1 and 2
I think for the time being you should not perform sex without telling any person about these symptoms and them might be STDs as you might risk getting sued if you infect other people and spread STD

Please update

Hi, just some detailed information to highlight the risk from unprotected Oral Sex for other readers:
.
" Some people mistakenly believe that it is rare or impossible for sexually transmitted infections to be spread through oral sex.
However, it is possible to get a sexually transmitted infection (STI) from oral sex; in fact, some STIs, such as genital herpes and gonorrhea, are more commonly spread through oral sex than other STIs, such as HIV.
Worldwide, about 1 million new STIs are acquired each day, according to the World Health Organization (WHO). It is essential that sexually active people understand how STIs are transmitted and how they can reduce the risk of spreading infections.
Oral STIs
Many STIs may be spread through oral sex.
It is possible to contract many STIs through oral sex, as oral sex involves close contact and often an exchange of bodily fluids.
STIs spread through contact with bodily fluids or skin that is infected with the STI. Different STIs spread at different rates and through various bodily fluids. The chances of getting an STI depend on a variety of factors. "
