Hmm. I tend not to focus on stuff like this, I'm not really that big on identity related stuff, and I usually never bring it up but this is a relevant thread so here comes a relevant response.
Yuh huh, I'm one of them, specifically on the asexual spectrum, attraction is not completely absent but I do experience it to a certain extent, towards the 'G' part of things. I can't pinpoint it exactly, hard to describe but it's not that big a deal for me.
As for the acronym I think using LGBT, LGBTQ, LGBTQIA, etc, and all its other variants is kind of unoptimal, and not because I don't support it, I fully support the demographic, but because it can tend to get increasingly verbose for lack of a better term and there's always arguments about inclusion or what means what. This would be solved by just using GRSM - gender, romantic and sexual minorities. Includes everything you can think of under the sun.
