How to find good people to play with?

I know there is a PSN ID thread and ive posted in it. Im wanting advice on how to find a good mix of players to play with. Do you meet people in forums, real life, in game, etc? Im new to owning a ps4, ive been playing since launch but got tired of using the bf's. I only have a few friends right now and im finding it hard to find decent ones. Im a 28 year old female so im not wanting to play with 12 year olds lol. Im not trying to throw the "because im a girl" card but i swear its harder. I have to weed out the ragers, youngins, and pervs haha. So give me some advice, how do i go about making good gaming friends?

Thanks in advance to anyone who replies, i really appreciate it.
