What you said about chemistry is something I have said for a while, about both online and offline dating. Chemistry is not physical attraction. Chemistry is what you have in common, how easy the conversation goes, etc. That, in my opinion is also not something you discover after a date or 2. You might - but so many people don't want to give others a chance and reject the other person after one date. I call those 'one-date wonders.' That really great date I have with someone and then she either ignores me or tells me she's not interested. But no, looks are not chemistry. I don't care how good of a body she has if she cant hold an intelligent conversation.
