A Lecture in the Classroom of Life

I'm a professor in my 40s who's been dating casually for months now. Last night, things got more intimate than expected during an after-dinner drink with Alex, another faculty member whom I've developed a crush on lately. We ended up at his place, and let’s just say the conversation about our classes was quickly replaced by a lecture in the classroom of life, literally in his living room. But here's the thing: it felt like we were both students eager to learn something entirely different from each other. Is this normal for middle-aged academics? What do you think?
