Im a 19 year old Traditional Catholic guy. Very mature for my age ( melancholic scholarly type) I'm thought about the priesthood, but a part of me does think God is calling me to marriage. One big problem is that the vast majority of Catholic women I know are either Feminists or NeoCons. There are very, very few seriously Traditional women out there, so a guy can't be too picky. There are some girls I'm interested in who are a couple years older than I. What's a reasonable age gap?
Everything Nadir said kind of "goes without saying" when it comes to finding a relationship -- the topic is much broader than just age. But since that was the specific topic of your question, I was strictly addressing the age issue.
But I forgot to mention something else -- "a part of me does think God is calling me to marriage". Hopefully it's not a part that resides below the waist. I know that's a bit blunt if not crude, but I'm serious.
My point is: don't think that priests, or men called to the priesthood, are fαɢɢօts, asɛҳuąƖ (as in: not interested in sex, or no sex drive), defective in testosterone, and/or not attracted to women. Because that is not true! As at least one individual pointed out, if you
aren't attracted to women that might be an impediment to the priesthood, and the seminary shouldn't want you, because perhaps there's something wrong with you (such as the emotional/mental/spiritual disorder of ɧoɱosɛҳųαƖity).
A priest is a man like any other man -- except he makes a noble sacrifice of having a family, and unites his whole life with the sacrificial life of Christ, up to and including His Passion and Death.
A priest is not a misogynist. He doesn't hate women, he just loves God more and wants to serve Him in a special way to help bring souls to heaven.
It's not that a priest isn't attracted to women -- it's that he has built up virtue (both natural and supernatural) and lives a life of self-denial and mortification -- perfect chastity is only one of the ways this is manifest. There are many other virtues as well that he will practice.
Long story short, every man considers marriage or is attracted to the idea of marriage to some degree, because A) it's natural, B) the institution of Marriage is good and created by God, and C) it's the "default path", or the way of all flesh, as it were. The only way you should reject marriage is for something higher, such as to give yourself to the religious life, the priesthood, or even a special apostolate/calling as a single person (single people have more time than anyone else, and a huge temptation and ability to be completely selfish. So watch out on the "single" vocation...)
But that is why you try out a vocation to the religious life/priesthood FIRST, before you get married, and see if God wants you. Then, if He doesn't, you can go in peace and go find a wife. But even then, if you don't manage to find someone suitable even after a long period of time, it could be that God is not calling you to marriage. Don't settle or be desperate. God won't call you to marry a non-Catholic, for example.
