Is it normal to be against been straight ,while been so yourself.

Makes sence. I think being asexual would make some things like sexual needs much easier.
I'm pretty sure I am demisexual, which means I'm not quite asexual, but I feel no interest in anyone until they show a lot of interest in me and I feel they are worth my time.
In a way I think it's harder because I have no sexual or romantic interest in practically anybody, but I do still get those urges. Not having them would relieve a heavy burden.
I seem to have a normal sex drive but I don't care about random girls the way most my friends do. I think I would like a girl that showed a lot of interest in me and put in effort to know me but otherwise I feel better off alone.

Sexuality is a lot within the mind, I believe that you can work with it. If you have issues such as sex addiction and your behaviour is harmful to you or others you could put yourself on chemical castration.

castration may help in that scenario.
