likely cultural. There are a lot of (possibly "extreme") male environments where males DO provide emotional support to each other, though probably at a lower throughput that the "typical female" friendship, and where they don't, it's empirically dysfunctional -- for example, groups of men living together in submarines, deployed in the military/bootcamp, prison, but also some less extreme stuff like fraternities.
On the other hand, for men, finding yourself a "band of brothers is "your job". If anything the cultural defect that we don't tell men that it's up to you to create your own band, and that we don't give them the tools to do so (note my examples are almost all "men forced together by happenstance"). There is a cottage industry of male support groups that is starting to address this that's getting really popular, if you want a rec, I'm doing one starting mid-next-month, I trust the pod leader, he's my housemate, and really good at this.

As for the sex differences, I suspect both men and women need approximately the same amount of emotional support, just that in our culture, men undershoot how much they think they need (often by a factor of infinity) and women overshoot.
