Is it normal to hate sex?

i know ive heard of the greatness that people feel when they have sex, but ive never felt great about it. im actually almost repulsed by it. im having a difficult time dealing with it, so as a serous asker what are some reasons certain people may hate it? is there something wrong for me to HATE sex? if so i know it will cause problems in relationships, so could i be happy celibate? ill appreciate help on this subject as weird as it may be.
