How do I get my boyfriend to be more dominant?

I don't mean dominant as in controlling, more just confident. I want him to act like he WANTS to hold my hand and kiss me. I know he does (he's told me) but he always just holds his hand out or brushes his hand against mine and makes me grab his rather than just grabbing mine and I wish he would. The other day I basically just pretended like I didn't notice his hand until he grabbed mine, but I still don't think he's catching on. Also, he treats me like I'll break if he touches me too hard, and I hate it. I love that he respects me and isn't abusive, but I'd like him to show me that he's a man. Before we started going out, he used to be more flirty. For one, we were both ticklish, so we would poke each other's sides. When I went to poke him, he would trap my hands in one of his and tickle me. I liked that he was showing that he was stronger than me, but one day he poked me when I was at my locker. I hadn't even known he was behind me, so it scared me pretty bad and I pretty much jumped out of my skin. He didn't mean to scare me, and he apologized, and I said it was fine, but he hasn't poked me since then. I like that he's gentle, but sometimes I wish he was a little rougher and showed that he's stronger than me. That's part of what's attractive to me about men. I know this is kinda long and confusing, but basically I just want to know how I can get my boyfriend to flirt with me again and take more control of our relationship. I'd prefer other ideas besides just telling him because I already tried that, but I don't think I explained myself right. Thanks for all the help. :)
