Being genderless is something I've heard of before, but I wouldn't know how to achieve such a thing, I'm not having much luck following my own advice here, but the best policy is to just tell them the truth, if they accept it or not is pretty much on them. Look up androgenous styles, they're actually in right now on the fashion scene. The important thing is to just be yourself first, helping others to understand will get easier with experience. I have a close friend who seems to be moving in the same direction, but with her it isn't that she made a conscious decision, she's just being herself, and as it turns out, there's not a major drive to be either masculine or feminine, and I think that's the best way to explore it.
This is easy for me to say because I've practiced meditation for a long time, but at a safe time and place, just sort of turn off your gender related social filters and see where it leads you, I did this and gravitated towards the feminine pretty consistently, perhaps you, like my friend would experience something more neutral, as much as the cis world turns it into something else ->-bleeped-<- is about being who you really are, and either ignoring entirely the social norms, or if you find you do fit into one of the two molds available, altering your presentation so that everyone puts you in the right one. There are probably others here who can help you more with the specifics of being gender neutral or androgenous than I can though.
