Yeah the experience was quite nice. I plan to post a report on it soon. Indeed, I managed to connect with her. Finding girls who understand English in quite difficult in HG / 141 / brothel / sauna scene so I have given up on having any decent conversation with them. I don't speak anything else than English so it was a welcome change for me. I felt I paid more because there were few girls who were sexier than her and were asking for similar price (1500 - 2000 per night). As I said, that being my first time in Neptune II, I have no idea of price range. So initially I was holding out for lower prices (1000 - 1200) but gradually increased it as none were offering overnight in that range. But as an after-thought I was curious to know whether that (1500-2000) is the normal / reasonable price.
BTW, I took her to my hotel but I was spending on the hotel stay anyhow. I didn't consider it as an mongering expense.
Of course, spending only on meals and entertainment (and a few occasional gifts) is the best way to get GFE and is my preference too. But as you said, it takes time. And unfortunately, I am not one of those men who don't have to try hard
