I find it harder to make friends with males because it's often hard to find a good connection. I'm 47. But I have made good friends with other males once we find a groove (often based around humour)
I've often been surprised about the things other males think about once they open up. Initially some males can seem quite one dimensional.
I got a lot of crap when I was younger because of my friend choices. Teenage years? My parents wouldn't trust my friends. Didn't like me hanging out with them. Folks assumed I was having sex with this group of guys, which was really weird as I didn't generally date within our core group. In many areas, it simply isn't socially acceptable. Yet it is completely socially acceptable to be somewhat possessive of your romantic interest, up to and including forbidding them to have opposite-gendered friends. For men stuck in a "macho" society, it can signal that they might be gay and made fun of for it (and I don't actually understand why). It sucks, and I'm quite happy my spouse isn't one of those people.
I work pretty hard to maintain some normal interests, enough that I can chat with pretty much anyone. I do find deeper relationships difficult though, as there are fewer people who share my real interests in my area (or even in my cohort of long term friends). Finding those people is difficult.
Long term relationship is easier when you can talk about trivial day to day stuff, because is not enough serious stuff to talk about normally - after a while you just said it all.
Maybe I'm really strange here, but do guys even have lady friends who are not their relatives, who are not their co-workers, and who they are not trying to date?
Edit: Downvotes? Is there something controversial about being friends with women to just have enjoyable conversation and platonic interaction without some sort of ulterior motive?
