A little long , so please bare with me , really need your help :)

First post here ,please dont crucify me :D So , here is the story with me. Im about to take a girl to a Shisha bar one of these days. She is a blonde 22 yr old German , and I am 19. The thing is , I was bored like a week ago , and one night I made a registration in some German dating site , for free just to see what happens. Didnt expect much but I checked and saw that an anbsolute stunner had send me a "kiss" , so I started messaging her. She was a little weird , because she kinda felt like I was rushing it , and she was a little cold I think. She asked me questions like im on an interview , but then she approved of me and when I asked her about this "date" , she said she is down , BUT she lowkey snuck in a message if I would finger her THERE. I was a little shocked and basically said , well yea if you want to. Then we havent brought it up again but I was a little suprised. She doesnt seem to be some sort of Camgirl , but I suppose she is on there mostly for sex , which I dont really mind. Also , judging by her appearance , because she doesnt really look like your average girl , she has a hot face and body and HUGE tits , 99% sure they are fake , not that I mind but I felt like saying it so you get an Idea. Soo my whole question is , should I even do it? Or I would lose from this situation if I dont? The girl seems to be into the idea , I would have loved to try and make a girlfriend material outta her , but she probably is a whore or atleast not a girlfriend-type of girl. Also I feel a little nervous , cuz im a virgin and this will be my actual first time and I feel a little unconfident. I have been going to the gym the last moments , but Im still far from my goals. About me - I am not obese in any way , im just kinda average , but I feel kinda fat when I take off my shirt , when its on I feel normal , its weird. My face isnt ugly at all I think , but its not on a model s level aswell - I would give it a 7/10.Also im pretty tall - like 2 metres (6'6) so I guess that s good. Since I have never been with a girl can you give some advice , what you would do in my shoes - would you even go , and if you did , how would you behave? Cuz my heart is racing right now , I feel like she might be the one to make me a man finally and a part of me is excited as hell :P but Im not sure if its right. I am indeed forcing it , because I have little patience left and she really interested me , and its better to fuck her than some hooker that will ask for money I guess. Also would appreciate some basic stuff , like hygiene tips - should I shave stuff like my legs for example ,chesthair and stuff like that cuz im inexperienced and am not sure what girls like , and If i get some action I dont wanna disappoint obviously, and for example if she makes a move on me or I on her would it be easy to just take her home and seal the deal? Please guys just give me whatever advice you can because im nervous and inexperienced and these two already have cost me like a dozen great girls that were interested in me but I would fuck up due to a multitude of reasons.. Soo I really dont wanna fuck this one up too...unless you advice me not to go. I really want this , but if you say its unreasonable I would totally understand , but still , I just wanna be prepared anyway :) Also if any guys that have had similar experiences with such a type of a girl are out there , or if there are some Germans on here that can give their piece of advice about sth like this , please do :)
