Celebrity crushes and animal magnetism

A questions to anyone who is interested and willing to respond.
I am curious about celebrity crushes, but this is really just a polite/innocent way of saying 'celebrities' (or any person you do not know or engage with) who you would really like to fuck. A celebrity for whom you have a strong, a****l attraction to. Personally, I have experienced this type of strong a****l attraction before, but always to a person I was face to face with, or at very least in the same room. I don't know if the attraction can be attributed to pheromones, body language, or what, but I am talking about the really strong feeling that you want to, or even NEED to, for your own personal well-being, have sex with this person. Recently, I have this strong reaction to Christine Tizzard, who is the host of Best Recipes Ever, a show on the CBC in Canada. Weird, I know. If you are curious, you can watch clips at http://www.cbc****bestrecipes/
I don't know what it is, but when I watch the show my balls start aching.
