I have questioned my calling also, as to celibacy. I overthought a lot of things. I have finally realized that my calling is not a life of celibacy, even though I am single right now, and that it is just a matter of time before I find the person God has saved me for. Even though Paul says it would be best for everyone to be celibate as he was because you wouldnt face the troubles of marriage, Jesus himself and Paul says that not everybody can do that, or has that gift. Paul says its far better to face all the difficult challenges that marriage has to offer than to remain burning with passion. I really think its safe to say that if you have any sexual desires or any desires to get married, then God has not called you to a life of celibacy. I believe only those who have that gift will be able to go on without and if you are troubled sexually or troubled by having desires for marriage, then celibacy is not for you. You say that you want to remain single because of past dissapointments. Although it is very understandable, it is also a very bad reason to renounce marriage. You say you are more of an introvert, but what does that matter? There are plenty of happily married introverts, or has God called all introverts to a life of celibacy... no way! The thing is, if it is Gods plan for you to be married someday and you are trying to go against that because of past dissapointments then I believe you will be very dissapointed all your life. You are living in fear and although the thought of getting hurt again can be unbearable, we need to have faith in God. God does not call us to walk in fear, but in faith and hope. Many times I have also said the same thing about the neon sign, but where is our faith at? God wants us believe in him even when we cannot see. You need to pray about it and believe that God will not end up letting you hook up with somebody who is not meant for you. Just because God can bring two people together, does not mean that we have to stop working. Marriage is a lot of work, but we can be assured that if we put forth effort, it will work out. I dont believe for one moment that God will lead us to marriage, and he didnt intend it to work out. Put away the doubts, the fears and go after your desires because it may be the gift that God has given to you and wants you to go after. We will live dissapointing and unsastified lives if we live outside what God wants for our lives. I honestly cant believe I am writing all of this because I am the person who was once confused and unsure of things, but God is definitely revealing more things to me everyday, its amazing.
