Dating American Men In London

Is the dating etiquette different in London than it is in the USA?
Ok, so I met the man of my dreams on Saturday at a nightclub in Las Vegas (that just sounds bad). We talked for about 2 hours and he gave me his card. Only one minor problem…he is from London (he will be here for 3 weeks).
I don’t know anything about the UK or the culture. In the US, it not uncommon for a girl to ask a guy out, is it the same in the UK? People say American women are more aggressive than women in other countries and I don’t want to appear desperate or give him the wrong impression. Is there anyone from the UK able to fill me in on the etiquette?
I gave him my number too, I told him to give me a call and I would show him around town. Should I just wait to see if he calls me like a nice little girl or go after what I want?
Girl give him a call. The reason women in the UK are less aggressive is because most are always so drunk they cant stand up..lol
Seriously give him a call your in the US not in the UK. I have a friend from the UK and she’s asked men out too.
