It's very hard to find consistent information on the internet, some people say no, some people say yes. I'm an 18 year old male and I've been dating a girl for the past 6 months. After having oral sex for several months, we discussed and decided that we both wanted sex. A few weeks ago we had protected sex with a condom and we we're both no longer virgins. However, the condom broke and we thought we better get checked for STDs just in case on of us had one. Both of our tests came back negative. Earlier today we both discussed whether she should go on the pill, so we don't have to worry whether the condom breaks again. She was going to go on the pill either way because she has a inconvenient menstrual cycle and bad cramps. Anyways, we will soon be having unprotected sex, but I'm now curious. Can either of us contract an STD if both of our tests came back negative?
Basically:
Can my partner and I contract an STD from unprotected sex when both of our tests came back negative?
Thank you
