You have a good point there. Women do tend to put together social events. The private residence parties you describe are usually better for meeting women than standard daygame, night game, or online game. Any man is going to have more of an opportunity to shoot their shot at a private residence party than in daygame, night game, or in a tech-based method.
It's possible to get invited to the types of events described without being friends, though you'd be a higher level acquaintance. It'd be possible for a male friend's girlfriend/wife to invite an unattached man to an event or get invited to an event from a female co-worker. The line between acquaintance and friend can be a bit blurry.
When a man depends upon his male friend's girlfriends or wives for introductions, he's often disappointed. Women in committed relationships tend to run in social circles with other women in committed relationships.
Men can get laid consistently without an FWB. Those are men with girlfriends and wives (first few years of a marriage). Few men can consistently get 1-3 night stands from nightlife venues.
The thing is this: When an Alpha male has "female friends" its not the same thing as a beta male having female friends. All the female friends an alpha male has, is acquired by the fact that he attracted these girls into his life, whether he picked them up during cold approach, met them at college, or met them at clubs, etc.. Most of my female friends I've banged before. If I hadn't, its because I wasn't attracted to them.
I was goign to make a whole post about this but I kinda added it into another post: Having a nice apartment in a skyrise not far from clubs/bar scene = the ideal situation for any man who wants to have a "Dan BIlzerian"esque lifestyle.. You know how easy a VIP booth and bottle service at the club translates to multiple diff girls who don't even know each other coming back to your place?
These dudes on Sosuave are so clueless, I have rarely seen anyone besides 1 person mention this fact alone. and That dude was prob the only other dude who has posted pics of women/plates hes got besides me since i been here. Shoutout to him

If you're a dude and you consider yourself any type of good with women, Don Juan, Player, etc.. you better have at least 5-6 women you can hit up to have sex with or to invite to your place. No excuses..
Theres no difference between FWB and Female friends besides the fact that most guys dont bang their female friends or only keep females as "Friends" who they aren't attracted to enough to bang. Having female friends is the sht .. You ever get laid b y a chick you considered a friend jus cuz she met a guy she didnt like who gave her an unpleasant time before they broke up ? Unexpected pu55y . Thats not even a perk.. Theres bigger perks of havin female friends like i Mentioned. I might make a post about it.. i have a really good story to add..
But overall i think its just something most dudes wouldnt understand until they experience an abundance of women in their life besides their 1 or 2 FWB's.. or random lays which is the worse... not having consistent sex is trash
