I've managed to get to start talking with 2 girls on social media. It's been going great but the problem is that they don't life in the same area with me so we can't date or hang out. I've been thinking of getting their trust and then going to their city and going for a coffee or clubbing or whatever she wants. But idk if I should try to be flirty. I mean I haven't talked this way with girls for years since I ha studies so I didn't focus on seduction. Now I try through text jokes to have a good relation with them and then if I'm lucky I get to get a relationship with either one of them. How to know when I should get more personal ? For example

Girl 1:started with only texts and jokes, started every night sending selfies and vocal messages and talking

Girl 2:started the same way as girl 1, but goes on as playing video games together and also trash talking her in a jokingly way (I've also said to her if it brothers her I'll stop)

I really like girl 1 in a sexual way and I wanna make that clear.

Girl 2 is also beautiful and has an amazing character but she lives way too far from girl 1 I am talking to.

Idk what to do I need some advice. I've been talking with both for 4 days now. Ik it's early as many have told me to decide but I really like (love) them both and I don't want to mess this up. Please help me someone I want your advice and insights if you've been in a similar situation
