About to begin my journey

I have loved dance for as long as I remember. I never had formal training and have always been too shy to join many classes ( have done 3 belly dance classes). I love the athleticism and grace of pole dancing and have decided to start, regardless of the doubts I have about my body, sexuality, opinion of others etc. I have the space finally and the money to get a quality pole. I have looked at the X-Poles and my main question is the difference that diameter makes. I am 5'6 and now 125lbs (quite drinking beer and amazing things happen).I am ready to invest in my dreams but want to be informed and know what I am getting in to. I am all about safety and proper form. Anyway. I am ready to start my journey and could use some advice in picking the appropriate pole. I am so excited about starting online lessons and practicing at home, especially after taking a "taster" class at a studio downtown (my crazy night schedule doesn't allow me to go regularly but I hope that will change eventually). Thank you to all members on this site who have braved youtube to bring to my attention that I am normal, healthy, and can dance just for me. Cheesy but I am going through my quarter life crisis so big decisions about empowerment have left me breathless. Thanks for the advice and support, looking forward to continuing membership. Yumchen
