you have nothing to worry about!
i still remember my boyfriend & i's first date... we had gotten to know each other pretty well at school for about a month, and one day he decided to ask me out on a date.. and well, he picked me up, gave me a rose and we had fun! it was awesome! BUT when he dropped me off, he was so nervous he didn't get out of the car or even lean over to hug me. i didn't get offended, i just abruptly joked about it in a text later on and said what, no hug? and he admitted to being too nervous!
you have totally nothing to worry about! you may not be like me, where i'm sometimes up front, and i'll tell a guy i like him after i get a few signals that he probably likes me too.. but sooner or later you'll get some signals out of him! think of it this way, he's the romantic, caring type

and those i find are the best!
