I would still dispute that the regret is from the action and not the consequences of those actions. Obviously being in close quarters with someone increases the likelihood of having sex. That's just a natural thing which is why parents used to warn children about making friends or being a friendly with someone of the opposite gender. It can set the stage for a sexual encounter that otherwise may not be intended. That's not the same as tripping and falling into someone. That's you intentionally setting a stage and allowing human biology to play out. The problem is always the consequences of it not the action itself. If it's a co-worker perhaps work becomes uncomfortable around them. If it's a neighbor now you have to be constantly worried that the secret may leak. Consequences not the action is what drives people and their regrets.
