I didn't read any responses, so I don't know if someone else has already said this or what arguments might have been made.
If being celibate is what you want, then it doesn't matter if you are called to it. No one has to be called to be celibate. No one has to be called to be married either. Generally speaking, both are options to us all. Is there a calling to be celibate for some? Probably, but I would think that would be for people who either don't know what they want or people who might prefer to be married but God has other plans.
As far as not having a healthy view of sex, that's something that needs to be addressed whether you are planning to be celibate or not. And it is not a reason to make a personal commitment to life-long celibacy because if whatever is causing your sexual problem gets healed and you meet someone you love, then you are facing the fact you made a commitment or vow or whatever you choose to do in regard to this. God desires that we be whole, complete, and healthy, in all areas of life, including sexual, whether it is something that is going to be part of your life or not. I don't think it is something you have to rush in to solve right now. It's ok if it takes a while, and it could be that other areas of your life need to be healed first. It could also be that if other problems you have are resolved or coping skill are gained, then the sexual issues might resolve themselves. Maturity also will play a huge role in this.
If you were called, then you would know and would not need to ask. The option is still there for you, called or not. I would hold off on making any personal commitments though. Celibacy is right for this season of your life. It might always be right for you. Then again, things might change and marriage could become a very real and healthy option for you.
You don't have to have the plan for the rest of your whole life right now. Live one season at a time.
