communication is the key here, why?, because everyone is different. Most women do like to take it a little slow at first, but even then there is always room for a kiss. One single kiss speaks volumes it says thank you, I like you, I want to get to know you better, when can we see each other again?
As for sex, I believe that should be when you both feel right about it. It should be unplanned (yet use protection), and it should be passionate. Women want to be respected but we also want to be worshiped in the bedroom.
Again, communication is key, and this is one of those places where there is little room for assumption errors. If you feel the least bit unsure, then breach the subject with something simple like "I'd like to kiss you, would that be ok?" or "how do you feel about taking our relationship to a physical level?" There is nothing wrong with these questions, the are legit and respectful.
best wishes!
