Lately I've been setting up meet-ups via OKC/Tinder. The last two I've been able to escalate, make out and then get them back to my place, the third we just made out. Sex has been denied and I'm worried that I will have to take them each out 1 or 3 more times before I can close. What's everyone's take on this? How long do you wait? When do you draw the line in terms of your time and money?

TL;DR - Need plate advice....I can easily get a girl back to my place and make out, but I'm worried how many more times I have to meet up with them before I close.

Edit: I live in the city (no car). I set up initial meets for weekdays only (been stood up and flaked to much to set anything up on a fri or sat night). I always pick a bar close to my house and one where I can easily escalate (i.e. lounge type, sitting next to each other). Dates are set around 8pm.
