I'm a male and unlike many I don't find play pleasurable, is there something wrong with my physiology?

I currently own a ********* vibrator, I bought it because I read that stimulation was really pleasurable in men, but I find no pleasure, just a feeling of discomfort. I'm wondering if I'm not feeling something which I'm supposed to feel or is it that is simply that play is not for me? I'm a straight young adult.
