Is there a name for having an obsessive interest in new topics for short periods of time?
That's great that you have this ability -- it's your "special power".

I don't believe there is a special term for "intense preoccupations with narrow subjects", but such behavior is a common, but not necessary, feature of Asperger Syndrome or AD.

AD does occur more often in men than women. According to this paper, prevalence in men is between 2-4X greater than in women.
