Sexual abuse in childhood especially has a strong chance of being manifest as unwillingness to come close to a loved one.
The memory of the physical trauma that he/she went through as a child is often enough to make any thoughts of intimacy abhorrent or scary to the abused person, even as an adult.
This could be because subconsciously the person feels that he/she was in some way responsible for the abuse in the past, that he/she may have encouraged or invited, so to speak, the heinous act.
What you can do to in such a situation is to regularly appreciate their achievements and attributes – no matter how small they seem.
Let the other person know that even though you find him/her attractive and are deeply in love, you are willing to wait till the time they feel they can open up to you.
Thus rather than give in to such negative thoughts, it is far better that you and your partner seek out someone who will be able to help you through a complex situation and prepare you for a mutually fulfilling relationship.
Since asexuality is rather unknown, it is subject to a lot of misinformation and ignorance. It is possible for an asexual person to not have sex and be celibate, and it’s also possible for an asexual to have sex and not be celibate. It is a sexual orientation, like heterosexuality or homosexuality, and like those orientations, it cannot be turned on or off on a whim.
Yet another far-reaching consequence of childhood abuse is a lack of self-worth or even a latent sense of guilt in the victim.
Thus your partner may suffer at times from a lack of self-confidence or even a crippling form of self-doubt.
