If you're having trouble thinking of stuff, maybe you need to look at how you're spending your time. If your only stories are about you and the same 2-3 people sitting in a room playing video games, smoking weed and drinking beer, then you're not living a life that most attractive women would want to be a part of.
As for non-situational topics, again look at your interests. Are you reading books, watching documentaries, learning new languages, going to dance classes, experimenting with meditation? Why not?
Here's a list of stuff I often bring up. Not just because girls also enjoy talking about it, but because it FASCINATES THE SHIT OUT OF ME and I can talk about it for HOURS really PASSIONATELY:
Psychology
Evolution
Male-female dynamics
Cultural differences (especially across UK, Europe and USA)
Biocultural Psychology (basically all the first 4 mixed together interdisciplinarily)
Music, Film, Cinema, Comedy
The nature of the Universe
Philosophy
SEX
A good progression is to start with simpler stuff like what's going on with your life at the moment and some funny stories from recently, and then work your way backwards to specific events in the past that relate to one another. Then you can draw general parallels about each others past experiences, which can lead to a more abstract general topic like male-female dynamics. That can easily lead to psychology, then back to past relationships, and then I always try to have the last 10-25% of my day 2 end with talking about sex. This builds massive amounts of sexual tension and makes her visualise having sex, probably with me. Then I just keep building that tension with good eye contact and slowing my words down, and then I take her back and wait for the k-close until we're in my room. Then I FUCK THE SHIT OUT OF HER!
