Dear Jihun:

I think it means that she is not interested in a physical, sexual relationship with you. Maybe because she believes that a physical, sexual relationship is fitting a marriage context and the two of you are not married; maybe she is not interested in such a relationship because she has negative feelings about sex and/ or about her body.

There is also the possibility that she is okay with sex outside marriage and she doesn’t have significant negative feelings about sex and/ or her body, but she is not sexually attracted to you. There may be other possibilities that are not occurring to me at the moment.

To examine different possibilities and figure out which one (or a combination of) is true to her, further discussions with her can be helpful. Asking gently and clearly can be very helpful.
