is it prostitution?

is it prostitution to take money from somebody who is expecting sex but then you do not supply? if i went out on a date with a woman and i paid for everything, i picked her up from her house or work, i paid for the nandos, i paid for the drinks then no i would not expect sex but usaully when i do this i get sex anyway. The fact that ive paid for everything don't mean that im looking for sex it just means that im a nice guy. I believe there are some woman out there who will deliberatly go on a date with a guy expecting him to buy everything down to the glass slipper then when you drop her off, walk her to the train station bus stop whatever you dont even get a kiss on the cheek or even a thank you most guys would walk away thinking what a cow she took me for a ride! ps i would just like to say this has never happened to me because my names not donkey and this aint shrek 2....i thank you. for more on this and the prevention of it please visit this link http://www.homeoffice.gov.uk/crime-victims/reducing-crime/prostitution/
