My advice is: don’t worry about it now. Worry about who you are, what your relationship with God is, and what God put you on this world to do and who he wants you to be. These are the most important questions in your life for the next 10 years, so you should delve into them, learn about all the things you need to learn about to answer them (including learning more and more about the faith, maybe reading St. Francis de Sales, St. Augustine’s confessions, starting to learn about Aquinas and the other traditions of the church).
The big question, marriage vs celibacy as a priest or religious, can wait. Why? Because whether you get married or ordained, that won’t happen for many years yet. And by that time, your priorities will be clearer. Are you the type of person who ought to invest yourself deeply in a few intimate relationships (i.e., raise a family for God), or one whose work for Christ should cover a broader field, touching many more lives? That’s the kind of thing that becomes clearer over time, as you grow closer to God and discern his will for you.
If it is celibacy itself that seems like the obstacle, know that this especially is a sacrifice that does become easier to handle later in life than it is in adolescence. And that, married or celibate, it will always require a lot of dedication to follow seriously the Church’s teaching fully.
