Sounds like you might fit on the asexual spectrum. Go to the Aven-wiki and look around. Celibacy is not asexuality but some of your ideas fit into that category.
On a side note, your libido is a function built into you. Unless you were born without it, you will always have it. There will be times where you become aroused and such - and you may not be able to control it.
Also, some people are naturally uncomfortable with intimacy and sex. H. P. Lovecraft is a fine example. You shouldn't be super worried about it unless it was triggered.
