Hello. Thanks for writing to us at healtharemagic A ruptured condom during sex counts as unprotected sexual encounter. Unprotected sex is always a high risk in terms of STD s. Ejaculation or not, has no significance. Furthermore, though some STD s may present with symptoms shortly after encounter e.g gonorrhea, chlamydia, herpes etc others like syphilis may present later (incubation period for syphilis is 3 weeks on an average). HIV, Warts and Molluscum may remain clinically silent for months before one notices them. Screening test for HIV (Rapid test) can be performed earliest at 1 month, before that it is can be false negative. Therefore screening is all the more important. I would suggest testing for HIV and Syphilis (VDRL) at 1 month and then again at 3 months. Herpes can be tested as early as 2 weeks; same is with hepatitis B virus. In addition to testing if you notice any urethral discharge, burning sensation on passing urine, genital ulcers/erosions, warts or growths or inguinal swelling etc you must immediately get it checked with a sexual health specialist.
