Psychologists are screwed up with this issue though. They will ask you if you enjoyed it, but if you were young then you probably enjoyed it until you found out why it was so wrong. Of course, if you are male, then the psychologist usually dismisses that it should be a problem.
I enjoyed it when my sister would have me do stuff to her, but it screwed me up so much when I got older that I warded off sex (still a virgin in way), developed trust issues, and still cannot form relationships. Seek therapy asap. You don't want to end up in your 20s with these issues because you didn't feel like talking.
