Hope it goes/went well Tyler. My first punt was last July and I was exactly like you, not knowing how to feel about it. Luckily in a way it all happened quickly for me. I hadn't really been planning to meet a WG but I came home from a nightshift and was horny as hell. I googled Local Escorts and found a girl 5 mins up the road. So from first thinking about it to walking through her front door was about 90 mins.
I suppose my overriding feeling was being nervous. Although not the best punt, even though at the time I thought it was amazing, she was a slim mid 20s girl who put me at ease straight away. So much so that it didn't seem unnatural that she was sucking my cock 5 mins later.
Hope you let us know how you got on.
