let me give you some professional advice: Get a tattoo on you "private part" a.k.a. your "weiner". Now, not only for this girl, but for every other girl you ever like, all you do is ask them if they want to see your tattoo. If she says yes, then there is a good chance she likes you. If she says no, then most likely she doesn't like you. Obviously this isn't 100% accurate since some girls won't like you but will want to see it anyways just because there obsessed with skin art or some other reason. And some girls that do like you might say no due to their being too timid or some other reason. But what your basically doing is asking them if they want to see you naked, but you're using a perfectly harmless question since asking somebody if they want to see a tattoo is perfectly normal. Good luck.
