Oh, what an interesting experience! "Oh you didn't know?" And then you gave it a shot anyway until you decided nope, just not doing it for me.
Yes, after a few experiences it can make you a little paranoid with girls who have a squarer jaw or more muscular arms/broader shoulders or some other feature you'd more often attribute to men (or, those lower quality pics). You just pay closer attention to the voice and usually you're fine - so long as that's natural, the other stuff is usually just "girl with a square jaw" or "girl who played more sports" (or girl with a crappy camera) and that's it.
