Is it normal that I hate sex and intimate relationships? I see it as something that is unnecessary in life.

You do you.

As long as your feelings don’t impinge on other people or their choices, there doesn’t seem to be a problem. Your normal is always going to be different than everyone else’s.

Hate’s a pretty strong word, however. If you simply would rather not engage in those activities, then you sound okay to me. It seems to me like you’re a sex-repulsed, aromantic asexual. That’s part of of the normal spectrum of human relationships as much as highly sexual, highly romantic people are. The former isn’t as privileged as the latter, though.

However, if you’re a resentful, seethingly angry individual that’s secretly envious of romantically and sexually partnered people, I advise you to seek professional, credentialed psychological help as soon as possible. Nothing good can come of denying what you really want (if you, indeed, privately really want it).

Maybe what you hate is the prejudice extended towards single people for not being partnered. That is indeed a problem, but that prejudice is about how you’re treated by society, not what you desire from society.

I’m going to believe you when you say you’re okay with not being partnered. All the best to you.
