Generally speaking there are four things you could catch from owo..
Gonnoreah
Chlymydia.
Nsu
Syphilis
Gonnoreah would show itself within two weeks usually with pain when peeing, a green or yellow discharge, pain in testes - I've had it, it ain't nice. Treatment is a shot in the arse which hurts like hell and two huge antibiotics to take .
Chlymydia can hide for ages, on fact many women don't find out they have it until they get pregnant and have a routine test done. You'll have swollen extremely painful testicles, sensitive tip and pain when peeing. You may have discharge. Treatment is a 10 day course of the antibiotic doxycycline.
Nsu is non specific uteritus which means you've caught some bug but they're not sure what it is, so they put it into this category. The presence of white blood cells in your piss usually gives it away. Treatment would again be a course of doxycycline. Symptoms vary, could be pain peeing, discharge, bollock ache, etc.
Syphilis, can't be arsed to go into it on here as there are three stages to it, again treatment in theearly stages is with an antibiotic.
Get tested asap , it's a simple urine test, hold your urine for at least two hours. Results come by means of a text.
