You may face early signs of Herpes , hpv , gonorrhea etc. And as u also got exposed to CS workers ,there are high chances of transmission , I will advice you to go thru entire
STD profile , so it can be detected at earliest .
And moreover , what is you problem , which u r facing , is u r worried for STD infections , I suggest better to consult then shy. U may discuss things freely and friendly, so that you can be helped by me and relived mentally .
