Hi Athena. These are issues that a good therapist can help you find where your heart is at. As many have said, there is nothing wrong with asexuality, and many asexual people who value relationships have healthy, emotionally intimate relationships without a sexual content. If you are asexual AND aromantic, you can still enjoy deeply satisfying companionship and friendship without a sexual or romantic bond, with others who are looking for the same thing.
If you are asexual but do have romantic desires you can have intimate relationships with romance but not sex with others who are looking for the same thing.
Some people have sexual interest but are aromantic, and have satisfying 'friends with benefits' relationships with others who are looking for the same thing.
And some people do have a libido and a desire for romantic attachments but are wounded or traumatized so that the thought of a sexual or romantic connection with an actual person triggers them.
Typically aces are not revolted or scared of sex, they are just not interested.
Typically aromantic folks don't dread or fear romantic attachment; they just aren't interested in pursuing it.
Having strong negative reactions even if you don't know why, is very often caused by suppressed trauma. That can be worked on with a therapist and be fully healed, so you go on to enjoy a healthy sexuality that is right for you, or a healthy asexualty that is right for you.
Good luck and much love to you. I can testify that healing, even profound liberation and self-acceptance, can and will be yours.
