Any person who is a fan of the British Pop Star Mika due to the fact that he is talented, sexy, and/or extremely awesome. Coined due to the fact that Mika will not discuss his sexuality. The idea is that one's sexuality shouldn't matter but that people should be liked due to what they do in their life.
I heard the song "Grace Kelly" the other day and I am officially a Mikasexual.
Someone who feels strong sexual attraction to milfs/cougars. Milfsexuals prefer older women to younger women as sexual partners. Milfsexual pride day is June 15th.
