I find it useful to keep hold of the distinction between sex and sexual abuse. For me, sex is loving or intimate (as difficult as that might be to create); if an act which involves intimate touching is not loving or enjoyable then it is not sex. Sexual abuse is violence. So the question for me would be; am I comfortable speaking to my therapist about acts of violence which I have experienced?

(Of course, there is the horrible contamination of sex which can occur if you have a sexual trauma history (flashbacks, body memories etc), so the distinction between sex and violence is not always very tidy).
