How do Men avoid getting attached or catching feelings casually dating?

My coworkers and I were having a random discussion, and this topic came up. One of my male coworkers (mid-30s) mentioned he’d go on several dates but still casually see one girl, while another said he’s casually seeing two.

As for the women in the conversation, we all agreed that we tend to focus on one guy at a time, once we’re interested, our attention is on that person.

I was curious, though, what’s the male perspective on this? Have any ever casually dated just one person at a time and managed to stay detached or not catch feelings?

I know women can be just as casual about dating as men, but it often seems like women are the ones who end up feelings more easily.
