Not really. Boys have about 14 to 17 times the amount of serum testosterone as girls and that does affect their felt incentives for things like competition. Culture can mute this but at great cost to boy's and men's health.
The idea that gender is separate from biological sex is very recent. When you examine its origin you find that it comes from Foucault and Judith Butler. Both were gay. It's unsurprising to me that that idea would come from that lineage. If you are gay you are confronted with a difference between what you feel and what society tells you from a very early age. In general straight people do not have that issue and would never consider drawing that distinction unless the concept is introduced to them.
