<human>: Could you distill the essence of the text into 1-3 sentences?

Okay so to start off I have no idea where to put this. 

My transgendered(MtoF) friend has recently decided on the name Lelaine(%). We are in some sort of close friendship, but she has pursued romantic relations with me, to a point. And I have reciprocated, to an equal point. The problem lies here: In the past, I "dated" a girl named Leliana(%). The experience was alright, but we did have an eventual breakup, and the emotional aftershocks led me to become asexual for a month or so after that, and furthermore reject any future relationships with any females whatsoever. I **POUNDED THIS INTO MY BRAIN.** No girls anymore, ever. But, now that this is happening, and their names are so similar, I fear that my brain will physically not allow me to enter any sort of relationship with Lelaine. (This cues the freakouts in part as well)While I am attracted to Lelaine currently, I feel that that will all change once she starts Spiro and the eventual estrogen, and I will feel nothing/the bad feels that my brain has been conditioned to accept.
<bot>: Is it possible for my brain to shut down attraction to a certain group  based on past experiences pounded into my brain?
