Of course you are. You are designed that way. Unfortunately, those hormones don't wait until marriage to start manifesting themselves. Either way, it is something that all people deal with, some more than others. It is a struggle and anyone who tells you otherwise is either mental

Anyway, part of our being conformed to the image of Christ is learning to put off the desires of our flesh, which is what you seem to be experiencing, in favor of what God says we should pursue. Seek ye first the Kingdom of God my young friend. God will bring you what you need in your life. Seek to be blessed of God with a wife, at the appropriate age, by seeking to be godly. Then, when you and a woman acknowledge a mutual attraction, it will be based on the proper foundation.
God bless
