Hi there. Though I'm a long ago over twenty, the idea of me as an asexual person crossed my mind when I was about 14-15. I had relationship with boys and girls before, but these weren't sincere - these were mostly out of curiosity. In addition, then I didn't know what love is. All what I've felt was disgust of being touched, kissed and hugged and regret of lying to a person I had been dating with. And then I thought, well, I had tried, ehough of this crap, I'll be alone to the end of my days (and so I'm). Days go by, but I'm happy being alone. Aromantic asexual, that's it. In the near future I'm planning to get a few cats and live with them in peace~
As for the main question, asexuals certainly have different view on visual-kei. This goes to the music and lyrics as well as to the looks and shows bands perform in the stage. Usually I'm not looking on that much, but there're exceptions of course. And I don't fangirl over musicians or their fanservice, too, but I admire a lot of them because of all they've done and continue to do for us. Though, sex in the lyrics doesn't disgust me, there're many kinds of sex in the lyrics. I'm saying that it can be very attractive and beautiful, tender and nice lyric. I like this kind of songs. In the aggressive and bizarre songs about sex there're... also can be exceptions. I like them if they're funny and cheerful.
Also, there're stereotype regarding asexuals. Some people saying or/and thinking that asexuals are ugly, that's why they pretending they're asexual so they can cover lack of popularity, be free and don't date anyone. I don't agree with that. I know people who are asexual and despite of that fact are really beautiful. I don't think I'm ugly either, but I'm asexual. I can do nothing with this. It's so unfair. Because of that most of the time I have to hide my identity from people (in the internet).
