Sex is not vile! Goodness.
The key here is to understand what God wants from you, not necessarily what you want from God. I hate to say this yet again, since lots of folks already tell you this, but … I think at some point it’s best to get some discernment help from a priest. Especially since you’re so young and such a new Catholic.
I’m really speculating here, and perhaps someone might clue us all in, but I’m not sure that the Church officially speaks of there being a vocation to being single. There’s vocations to religious life, to married life, or to the priesthood. While the word vocation can be used in various ways, those three senses are the way the Church primarily uses it.
But again, I could be wrong. This is what I think at present without actually doing specific research.
Edit: Tim Staples thinks the single life could be a vocation. Here are his thoughts on the matter: catholic.com/radio/shows/qa-open-forum-6014#. Go to the 46:40 mark for the question. Apparently Opus Dei has a focus on single people consecrating their lives to God.
