Is pink gay or not?

Many people associate pink with gay. But you can see many strait guys wearing pink ties or pink shirts.
Is this because they would like to be gay or they simply like the color and by this they reveal a more feminine side of them and by this concluding that if they were gay they would like to be play the woman role?
There is also a special category of guys that are not afraid to say loud that pink is their favorite color. I won’t put them in the second category, since they live their life on the concept: sex, drugs and
rock’n roll.
