"and help that be a self-fulfilling prophecy by not caring that it makes people looking for others who are naturally not sexual very uncomfortable to be considered under the same label."
Thanks for being among them. This is why I don't use that descriptor online anymore, nor go to online asexual communities.
There's a lot of people whose sexuality is NO, and being forced to share "safe" spaces online for their shared lack of sexuality with people who also say they're asexual but their sexuality is YES is awkward, uncomfortable, and off-putting.
AKA no longer safe spaces (or a safe to use label) for those whose sexuality is NO.
Currently, thankfully, people offline still seem to understand "I'm asexual" means "No, I do not want to fuck. Not anyone, not ever."
