I’ve tested negative but I am convinced I have caught an STD, all symptoms and timeline within!!

I had unprotected sex with a new partner over 7 weeks ago, pretty much from after the first week i had a slight pain on the tip of my penis and a small clear spot appeared on the penis head. After about 3/4 weeks I noticed what looks like two groups of around 30 small spots (look like fordyce spots) had appeared on the shaft of my penis, the doctor at the clinic said its normal to have them but these have 100% only appeared since this encounter. As well as this i have had flu like symptoms on and off

I have in the last couple of weeks had a pain in my testicles and head of my penis on and off, now I have had a few boils on my bum cheek one after another and a swollen lymph node in my groin which is quite painful, im not really sure what to do as like I say my test results came back negative from clinic but i feel as though there is some infection as a result of this contact

any help and advice would be greatly appreciated, thank you

everything u have is benign and not related to an std

@kim12266 thanks for you reply, could these be a result of the unprotected sex however not be an std as such? im still experiencing some pain mind so cant help but think there is something going on
