There's nothing wrong with wanting to remain single. I suppose some people might wonder if someone who doesn't want to have any relationship with anyone might not simply be antisocial, however. Most humans have a need for companionship. If you don't, more power to you. That said, you might find it easier to deal with those who think there's something wrong with you if you just said you weren't interested in a relationship right now and left it at that. No one has to know that it's a permanent situation.
