Hard to say here most of the activity was risk free.
I only see a risk in the unprotected oral. Which risks Gonorrhoea, chlamydia, hsv1, syphilis.
The only one of these that could cause symptoms like you have is syphilis. Does your test include syphilis? If so it’s not syphilis.
Syphilis is rare so I highly doubt it’s that if you haven’t tested but maybe if you let me know your full testing history I could help more.
Final thoughts have you been self testing ? It’s not a good idea when you have symptoms. A qualified Dr can look at the full picture not just STI. It’s probably time to look at other causes now.
