Well you are just 25, very young. Enjoy life, do crazy shit and don't ever commit at your age. I think there is something off with people that have children at 25, too, btw. It s a question of finding the proper timing.
Maybe your opinion will change in 10 years. I used to think it s awesome to be 45 and free and bang a bunch of women James Bond style, but now, yeah, it means something is not right.
I think it all boils down to life becoming pointless after a certain point when you don't have children. Nobody to pass things to. Just your own self and having fun, but isn't that a bit vain, after a certain age, say 40?
Not sure why but I guess what turns people off is that it signals to others that one takes his fun too seriously and has nothing to give. Essentially it signals being selfish and untrustworthy.
Don't get me wrong, this is very subjective and I know it's stupid but if I try to put it into words that would be it.
Another way to explain it is through some cognitive bias: when you have a child you adore that child and everything else looses importance in some capacity. So people assume that people without children care about unimportant things, since the most important of all isn t there.
I know it s all bullshit though. But trust parents when they say that life changes with a child
