This might sound a bit odd but I always get horny when I am shaving (my face). It has been this way for the last few years. I have no recollection of how/when I might have been conditioned like this. It is different from a fetish. e.g. I have a huge fetish with scrubs (not the show) and I get horny immediately on seeing them. I am curious if there are others who have such Pavlovian response. In other words, be aroused by something that is no way sexual or not in your list of fetishes.
