so a few months ago i got into a new (currently, long distance due to school) monogamous relationship with an absolutely amazing person. we're both cisgender girls, and neither of us have really done anything in the past apart from making out, so theoretically we should both have clean bills of health. we've talked about getting tested, and we want to get tested before we see each other again, since the tension is building and we want to be ready for whatever happens when we visit.
so, here's my query: if, after testing, we're both clean, would we somehow be at any risk for STI's or STD's? i know it's important to use dental dams (which i've already acquired some of) and whatnot to avoid yeast infections and the like, but if things were to get really heated/we were to run out of dental dams, what would we be at risk for? i've never had very good education on lgbtq+ sexual health.....i want to make sure i'm doing things right. if neither of us have anything, and we're not seeing anyone else outside of the relationship, there shouldn't be a way for either of us to catch anything serious, right?
basically, i need as much advice and information on this topic as possible. i know there's probably some resources on this website but i haven't found anything that answered my particular questions yet
