Strangely, I have a woman to thank for "discovering" the pleasure of ear-attention. Before I decided that I actually preferred men, a woman stuck her tongue in my ear, and I was IMMEDIATELY responsive!
Over the years, have not found many men into such attention. When I met my boyfriend, and stuck my tongue in his ear the first time,he laughed, cause it tickled. But with time, he has come to enjoy it from time to time as part of our foreplay.
Maybe two months ago, I was sucking on his nipple, and he bent his head to stick his tongue into my ear at the same time. OMG...it was so damned HOT
Not only was I intensely turned on, but he has never had better attention paid to his nipples..and other parts of his body... whew....
