As a writer, I desire conflict for my character.  Please, confront her with things outside her comfort zone, (those not outside mine hopefully?)<br/><br/>As for hard wired?  She does not fine men repulsive, but the idea of sex with them does not excite her.  A 5 on the Kinsey scale out of 6.<br/><br/>Her brother is outside this spectrum, of course. ;)
