A bit of money's always nice, so long as its not the be all and end all, and there are no hang ups/expectations on either side because of it.
He was probably out to impress last night with it being the first date , hence the fancy cocktail bar. Maybe you suggest the venue for next time? You both need to feel comfortable and relaxed on a date - maybe a quiet drink would be good?
About the sex, again I think the first time/few times people can be a bit keyed up and keen to impress, whereas you need confidence and trust to have real mind blowing sex, including an understanding if what does and doesn't work for you as a couple
So what I think I'm saying is, it's very early days, see how things develop but make sure they're going in a direction you're comfortable with. Sounds good so far, though!!
