... if this was a civilian or non-sugar relationship?
As you said, she's not a pro. So, I suggest you not try to compare your experience with her to what you've had with pros. As I've mentioned in the past, Sugar dating is still dating, albeit with some additional structure. If you had met her off the site and had this date, would you be looking for another date?
Next, you might consider the dynamics of sexual congress. New partners may often tend to be reserved, until mutual trust is built. It's impossible to know what her motivations are without knowing her background around sexuality, casual sex, and dating. Maybe she was raised in a strict household and thinks being too "wild" will make her look like a whore? It's not unusual for a woman to think being a "whore" is a bad thing (religious issues?). And they never realize that generally men LIKE whores - a lot!
Maybe she is slow to trust new partners and will need to see you consistently providing a safe and accepting space before she is comfortable letting out her true sex freak? Or maybe she really doesn't enjoy the activities you mentioned, or even enjoy sex, but she made a decision to play in the sugar bowl as a necessity to support her financial needs?
So back to my premise: If there was no sugar involved, what would you do? Would you invest your time into a few more dates to allow the development of a higher sense of trust and comfort, and perhaps her sexual appetite will expand? Or would you head back to the bar, church, party, social groups, etc. where you met her and try to find a new dating partner?
Either way, I think you can call getting to BCD with a SB a success, even if it wasn't the most memorable sexual experience of your life.
As they say:
Sex is like pizza: When it's good, it's really great. And when it's bad, it's still pretty good. :p
Life is good
