I've gone out with this guy a few times now, and yesterday I really felt like he wanted me to be more affectionate towards him. I wanted to, but I couldn't.

I mean, I
really, really like the guy, but I just couldn't. When I see girls all lovey dovey with their guys I call them "girly." I don't feel like I'm a "girly" girl. It's really weird cause with family and friends I have
no problem being affectionate. This was actually only our 3rd offical date. It was the first time we even held hands. He's never tried to kiss me or anything really. But like I was saying he did suggest that I could "lean on him" or "hug him" if I wanted to. I
really like him and I don't want to anything to scare him off, or make him think I'm not as interested as I have said I am.
How do I get over this, and just be affectionate around him? One more thing... what do guys think of girls that make the first move? I mean would it be wrong for me to kiss him first? Or even ask him to kiss me? Should I just wait for him to make the first move?
