Honestly I feel that a lot of women don't pay attention to where their **** are. Before I had a girlfriend, I enjoyed the random accidental boob touch, but now that I'm taken, and make my best efforts to stay away from **** that aren't my S.O.'s, I find that women have a hard time keeping their **** out of trouble. Unless they are purposely trying to get me to cop a feel, but I doubt that.
Actually, today, a co-worker leaned over as I was reaching for a time card and there was boob to arm contact. Didn't even phase her, but I definitely noticed and shamefully pulled my arm away.
I think she would have noticed more if you were a male, but she figured that since you are female, you'd understand how hard it is to reach things with out your boobs getting in the way.
I know mine get in the way all the time ;)
