I will admit, I treat the genders a little differently.
I tend to ah, give the 'fairer sex' a bit of the whole... gentleman treatment. I'll hold open doors, pull out chairs, offer help where I can, so forth. Mind you, I also have the habit of watching eye candy, so... fair trade? Idk, I just was raised to be polite and the boys of the family, well, those were the sorta values instilled in them. Don't hit women, treat them well, hold open the door, etc etc.
But I'll hold open a door for a guy too if he needs it, I'll help older men where I can. *shrugs* I might punch them in the arms sometimes and stuff, but, well, ya. More of a 'one of the guys' thing than treating girls or guys differently. If a girl was in that group, I'd punch her arm too, of course... usually gets turned to an ass slap?
The biggest thing I do notice different is... Well, I want to sleep with girls, duh, so I'll treat them a little more politely cuz, hey, points for that ; P But I'll talk with men and women much the same way. I'll flirt with guys, sure, but its more just being a tease more than anything. *shrugs*
Otherwise? I don't really treat them differently. So, yeah.
