Noooo, nooo, no,no...I mean, yeah, sure, why not, but you just have to go at it a tiny bit slower and more careful to get the groove going. From that moment on things will speed up, but not in the first seconds, rather once you have your general shapes established. That's when suddenly the shading becomes more and more powerful and you understand the way to control things. What appears slow at first becomes faster and faster something you'd otherwise couldn't or wouldn't have done that way or in any way. There's some totally pleasing magic waiting for you! And you especially, actually. You've got the goods for damn sure!
...eh...
Awww, rats!
Looking even more forward to your journey now!
OH, as a small inspiration, you might want to look at the mature section and my thread with the Ziegfeld girl. It felt a bit tough at first but by the time I was done about 2.5 hours had passed... that's all!
