Hi, depends which std. Things like Gono would almost certainly show symptoms in men but chlamydia would be less likely in females. With HIV we dont use symptoms.
Ive read that 11% of recruits going into the army didn't realise they had chlamydia or Gono.
Interesting statistic nether the less.
Would symptoms always be puss and pain when urinating for Gono and Chlamydia?
Yes puss would be the first symptom
