A lot can be figured out from the reviews and her profile, but here are a few things you probably won't find..
1) dry fingers anywhere actually hurt. Sometimes a lot
2) the "stripper slide" might feel great, but it is very risky and most of us aren't very appreciative of any attempts at unprotected anything. Of course, some offer this, but that is up to them...
3) "getting weird" might be better for a second date, if you can't find anything about it in her reviews. There's some stuff you can talk about, like a smoking fetish, or liking a more dominant/submissive partner, but any specifics are better handled in person. I hate getting overly descriptive emails, because even if I may have been ok with it, I am usually to uncomfortable to reply.
4) don't ask more than once, especially not in the same session. If we say no, it's probably because we can't, and no amount of begging is going to change that. But it might put you on a DNS list. Being a gentleman is much more likely to get you what you want, even if it can't happen today.
Just don't surprise us. Just because I like to be spanked, for example, doesn't mean I want a huge whack on the ass out of the blue. Ask, or gently build up to certain things, and pay attention to how she reacts. Part of the fun is being with another human being
