Ok.. So here's my story?

About 3 months ago me and my mate went to a birthday party.. ther was this lad walkin about he was nice but i thot he wud have a girlfriend, bout 4 hours later he was in out taxi home, he was talking to me sayin that my perfum was lovely, then i got out of the taxi and he slapped my ***, i met him again the next nite he came over to me and put his hand on my ***! we went out to the smoking area and he was there pointing at me to his mate, bout 10 minutes later we are snogging at the bar, he says the most beautiful things to me though like, your eyes are beautiful, what your wearing is amazing, and he isnt at all afraid to hold my hand or kiss me infront of his friends, and i have been seeing him everytime we meet at a club for the past 3 months, but i actually found now that i have feelings for him but i think he think that im just someone to go with when he goes out... how can i let him no that i actually like him without making me sound very desperate and without scaring him away?!
