If you don't want to come out yet, don't. And if coming out as a lesbian girl feels wrong, then don't do that. I can't say you'll get better reactions. It all depends on your family. But don't come out until you're completely confident in yourself.
Really, the best thing to do might be to explore your identity as a guy. Try binding/packing, guys' clothes (not necessarily masculine -- I went through an overly masculine phase at the beginning of coming out, but my tastes lie more in the effeminate). Maybe a guy's haircut. If you've come out as gay to some, then it won't seem all that odd. Just say you're trying something new if anyone asks and you don't want to say.
I'm just assuming you haven't done anything at all image-wise. While there's nothing wrong with wearing girls' clothes, having "long hair" (again, I'm just assuming, and it seems common), etc. as a guy, it seems like most people find testing the waters easier if other people see them as how they feel.
