It's interesting that you seem to divide your life into its previous period - unsuitable siex frequently, and it's porposed future stage - no sex at all.
might it not be better to simply consider sex as part of a fulfilling relationship?
That way, sex will occur only when it feels right for both partners, and you will be having sex for better reasons - as an expression of feeling, rather than looking for some nebulous and elusive personal vindication.
For that reason, I would be wary of saying to yourself - much less anyone else that tyou are celebate - which infers a lifestyle choice that is not for discussion.
I think if you make a decision that sex in a relationship will occur if and opnly when you decide that it is right for you - then that will lead to a more mature, safe, and happy way to be in any relationships - sexual and non-sexual - in the future.
Simply deciding to abstain from sex because it is not been a good experience for you is closing the door on a valuable part of life and love - and with some care and attention, you can find both - and the sex - in a proper partnership.
Hope you find a solution that works for you.
