Demisexuals have this sometimes. We aren't just abstaining from sex because we don't want to have one night stands. We are literally not experiencing sexual attraction towards ANYONE unless a close bond is formed, and sometimes even then we don't have it.
The hardest thing for people to understand about demisexuality and gray asexuality is that no, we aren't exaggerating when we tell you we barely have sexual attraction. When we tell you demisexuality is formed only under a strong bond, we mean it's ONLY then.
We are not "all demisexual". Demisexuality isn't about not liking one night stands or thinking everyone else is obsessed with sex. It's about rare sexual attraction formed under the specific condition of a strong emotional bond. https://twitter.com/scretladyspider/status/1274451511674843141?s=20
Or another way to think of it is what if you never saw the color red, but you never knew that, and then one day there was red? https://twitter.com/scretladyspider/status/1274136615900848131?s=20
Here are some people talking about what being demisexual means to them: https://www.cosmopolitan.com/uk/love-sex/relationships/a24401061/demisexual/
Recently I was on a podcast talking about my demisexual experience as well: https://twitter.com/scretladyspider/status/1277590979495813121?s=20
Here is a video (part 1 of a 3 part series!) all about asexuality and aromanticism:
So, no, you're wrong on every point, demisexuality has nothing to do with "not liking one night stands", the term wasn't invented on tumblr for people who just dislike casual sex, and demisexuals and gray asexuals are in fact an important part of the asexual & queer community.
