Desire for variety, and variety isn't just sex. Every girl I've been with represented a different kind of adventure. Each girl broadened my interests, made me appreciate new things, new types of music, new types of food, different types of dates, different conversations.
It takes a truly exceptional kind of girl to want to sacrifice and retire from those adventures, of "traveling the world", so to speak, and decide to settle down in one place for the rest of your life.
I found that with my wife, but I definitely had commitment phobia for a great while. The only time I didn't have commitment phobia before that was with my first girlfriend, but that was the result of inexperience and just thinking she was so amazing for the sheer reason that she was my first. It's easy to think a girl is your "one and only" if she literally is, at that point, your one and only.0

My boyfriend is against marriage after seeing his parents marriage break down when he was 10. I imagine situations like that can contribute to commitment issues and such.1
