I don't think a guitar forces you into a style, but rather that different guitars require slightly different approach. I've always considered teles and strats to be more physical (perhaps with Rory Gallagher or SRV in mind) than les pauls or any superstrat. You don't actually need to strum a les paul that hard, at least I've never felt the need, whereas every bit of violence towards a strat is an improvement in sound (unless you're playing "Wonderful Tonight"). A tele, especially, with bridge lipstick and neck HB, is a combination of extremes that I didn't get for a while, but I like it for Zappa-type weird sounds (though I don't think I've ever seen him play it).
I recommend trying out every guitar you can lay your hands on, even if it's realy cheap, looks or sounds worse than yours, or is pink in color :o . I broke quite a few inspiration barriers using the worst guitar I could find with an extremely irritating sound (BOSS Xtortion into a jazz amp or an old bassman with bright switch on and an open wah in front).
