Is this strange at all.......?

i have this female friend since my break up with my ex i have started to get a liking for since she is more type of girl buy the day i realize it. am not obvious mates with her i just know her well so one time i am out with her she stands next to me so close if i moved too turn i would knock her with my elbow. but the embarrassing thing is since i am not a virgin i've had sex done a lot of stuff but why in the world would i get a semi just for her standing so close too me every time she would brush me with her knee i know i like her but i can't like her that much.
