Well, Storm, impact can mean different things to different people. In general, when we say that something or someone has had a significant impact on our lives, we usually mean that it has profoundly affected us in some way. This could be in the form of positive experiences, such as meeting someone who inspires us or helping someone in need, or negative experiences, such as getting fired from a job or going through a difficult breakup.
Sex can certainly be a significant part of a relationship, but it's not the only thing that defines it. It's important to consider the overall dynamic between you and your exes, as well as the way that you've grown and developed as individuals over time. As for social media, it can provide a glimpse into someone's life, but it's not a substitute for real connection and understanding.
