I'm very sorry that you experienced such difficult times and had relationships that were abusive [described in your previous post] ,nobody should go through that.
The fact that you felt forced to go into toxic sexual relationships although you were not sexually attracted to your partners is awful.
I wrote in a previous post about the pressure on really young teenagers to be sexually active. In a different social context, the younger 'you' might not have felt that it was either expected or normal to have sexual encounters 'just because', or to prove something to yourself or others.
Teenage years are a time of questioning and should be ring-fenced as a time when you don't have to make up your mind for the rest of your life. That might mean teenagers thinking they want to have sex with boys, girls, both or neither; but there should be no pressure to do, or not to do, anything with anybody until they are old enough to make a considered choice.
Would you agree that it would be much easier for asexual people if there was less pressure, and less normalisation about being sexually active at a very young age? Maybe that's why being asexual in the past was no big deal - there wasn't the same expectation that everybody would be at it like rabbits
sexually active from an early age.
I don't recognise a social context (well, not a grown-up one anyway) in which people are frequently asked about their sexual orientation, are obliged to give an answer rather than tick the 'prefer not to say' box, are asked what celebrity they fancy..
It sounds like school, TBH, not the adult world.
It sounds like you've found your groove, MolkosTeenageAngst, and I wish you well in living your life the way you want to.
