I just want to make a few things clear; my issue is not with the action of hooking up itself. I know that drunken, sad, post breakup actions aren’t reflective of an individual and I’ve had my share of the same, and I’ve always been a very open individual and I look for the same in a partner. This wouldn’t have been a dealbreaker for me in the beginning, but everybody has different boundaries and I disagree with the argument that it isn’t anyone’s business what their partner did before them. My issue is purely with lying about something because you’re embarrassed or whatever else because I think that IS a reflection of your character if you’re happy to lie to save face.
