I see that you joined 2 years ago, previous post just like this one. You must be very nervous lol. It's ok buddy, just breath.
Im quite experienced in this hobby myself but have never seen Jennifer however from what I know she is a fine woman with a great attitude. You'll be in good hands. Bring $250, you won't need more than that. You might not even spend all of that. Tell her what you like, nothing these women haven't heard before but be respectful.
Im guessing you're nervous of two things - fear of being judged because of the stigma of paying to have the company of a women and the fear of getting caught.
Let me tell you a quick story. It was my friends 21st birthday. He wanted to go clubbing, pop bottles and get some "hoes". Before the night even arrives, he buys a Gucci shirt worth $600 for the sole purpose of flexing. At the club, he elects to buy 3 bottles of Ace which were $3000. At the club he attracts the attention of a pretty girl, starts pouring her shots and what not. They get to talking. Next thing, he's asking for the keys to MY 7-series so he can go fool around in the parking lot. It's his birthday, I said whatever here. When I caught up with him later that night, I asked him like every bro would "you get lucky" and he tells me she made him buy her food and all he got was some kissing lol. $3600 for a kiss. The girl never answered his texts. A week later, I head over to a spa, spend $250 and left much more satisfied than he did. Im not saying don't go out and have fun, what I am saying is your kidding yourself if you think there's such thing as free pussy. You pay for it directly or indirectly. I can tell you now, paying for it indirectly is much more expensive and may even give you the illusion you got game lol. Be real with yourself and understand what's going on.
Now for the fear of getting caught. Pure is a licensed adult body rub. Countless men walk in and out those doors every day. Its not completely risk free but like I'm 99% certain you'll be fine.
Now go and have fun bro stop being so nervous. Take a shot or two if you need before you head in lol.
