Can this be genital herpes?

I had I protected sex about a month ago.

Had std tests and it was positive for chlamydia, got treated for it with 1000mg of zithromax. Recently i started feeling stinging around my inner thighs and now i can some kind of skin rash

I have an appointment with a dermatologist soon but i would like to post some pictures for an initial diagnosis

No other symptoms such as fever or flu-like

Worth mentionning that where i live is quite humid and hot, and i do lots of outdoor excercise but i maintain a good hygiene

I mean unprotected sex

Use laptop

Here are the pictures

I think it is like dermatitis or fungal infection
