Need a guys opinion?

ok so apparently all i ever seen to attract are these creepy much much older men who verbally admit they want me. but i never go after them. the thing is i know yall love it when we talk like a guy and most of my freinds are guys but theres nothing between us. and my guy freinds love me like a sister and are protective of me but i dont date them, thier all taken and im not attracted to them. and its easy for me to talk about trucks, motors, sports ( u name it), huntin and fishin etc. but apparently every time i think ive got a good guy interested in me i lose them to someone else. and this kills me. no their not all jerks its just that once i get to know them it doesnt go any further. im not model gorgeous but im not bad. im witty, talkitive but not a chatterbox, im into sports like crazy. i just dont get why i cant seem to keep these guys. i thought yall didnt like ditzy girls. im not a nor do i look like one or act. so just what exactly am i doing wrong?
