My good relations with the ladies has been a learning experience for me. I'd say it isn't a learned behavior, but learning to recognize what was always there, like a latent ability.
Just this evening, I was fumbling around with the Dish Network remote at work. Who can find CNN among the umteen thousand channels, anyway? As I was paging through the damnable mess on screen, one of the ladies at work "accidentally" brushed my outstretched hand with her boob.
I used to be the guy that would pull his hand away if such a thing would rarely happen. Better late than never to have figured it out... You keep your hand there, man!
And, she keeps her boob there just a bit longer than an "accident".
What I've learned is the more open I am to such things happening, the more they happen.
