Hey,
I can't say I have personally felt this as I really want love and comfort from my therapist (which she also cannot give) but I think you are very brave to admit it and the feelings it brings up for you and I really commend you for that!
I think as a child messages can get mixed up meaning we relate to things in ways that may seem odd to others. I think in a way this is were a lot of sexual fetishes come from. e.g. if the first "sexual" self touch or unfortunately abuse, that felt pleasurable was related to a particular object, that can lead to seeing that object and feeling aroused by it in adult hood if the imprint of the connection sticks in some way.
