Aphenphosmphobia, Haphephobia, Haptephobia, or Chiraptophobia
Turns out that Wall-E has an issue with this...
TRF - I also have a slight fear of being touched, mainly by people I don't know. I have no problem shaking a stranger's hand, but anything beyond that makes me feel really uncomfortable. I do not normally sit next to people on the bus, even if there are open seats.
Even people I'm close to, or work with everyday, make me jump if they accidenly brush my leg, or put their hand on my shoulder. There's only two people I feel comfortable when they touch me: my husband and son.
