The feeling that there is something "wrong" with your vagina is, in my (unprofessional) opinon, a mental delusion after what happened to you. A lot of women feel "dirty" or used after a rape, they are worried someone will see it on them, they do stuff that can seem irrational in an attempt to make sure no trace of their rapist is left on them. Your issue sounds like it's connected to this: 1) you are afraid your rape did some damage down there so that people can SEE what has happened to you. This is likely not the case, as medical personnel are trained to see those things and the nurse who examined you would have noticed something was wrong. Or, not necessarily damage, but that someone will see what happened, which you haven't told people. AND the way you talk about warts etc. make me think you also (subconsciously) do think of yourself as a bit dirty or "sick" down there. 2) You seem a bit anxious with letting another person down there after having been forced once. That's not weird at all. I totally understand that. It takes time. Your body can crave sex but your head is not in on it, after what happened.

The vagina issue seems to be a mental thing. I would go to a therapist, especially if you haven't talked to anyone about this rape. It's a serious crime, some people struggle with it for a lifetime. Maybe you're lucky and five years was enough, but since you have abstained from sex I would try to solve the mental issues first.
