I think I'm a good candidate to answer this question since I went from a non-normal height(around 160cm) to a normal height(around 170cm) for men.
My new height has NOT produced more attention from girls. What I mean by this is that I have not noticed that girls shows interest more than before. This is obviously due to my looks, I'm simply a ugly guy. What has changed though is that I don't think as much about my height anymore. Before LL I used to think a lot about my height and I think girls could sense this insecurity. Obviously in my case a few more doors have been opened since I now have a normal height, so that girl who thought my height was a deal breaker will maybe not see it as a deal breaker anymore. But if you already are of natural height, you will most likely not be affected by this.
My sincere suggestion to all men out there who have a height that could be considered normal is that you will gain MUCH more by improving yourself in other ways. Start going to the gym, dress nice, drive a nice car and simply take care of yourself. If you don't get attention from girls with your current height, you will for sure not gain more attention from girls after LL. You also probably have thousands of dollars laying around to make this change possible, just make sure to invest it wisely.
