In my early years, in my ignorance, and being unread, unschooled and just being aware of my own body, thoughts and emotions and ignorant of everything else, I thought that a woman was there to just take care of my dick and somehow she would get her share of pleasure in due course along in the process.
And my girlfriend did just that, she took care of me night and day until one day I got the firm hand on my head and a strong push to her vagina. I was like "no fucking way." But she gave me that stern look which only meant "get to it."
It was a shock and a wake up call. The first minute was scary, confused and like "what do you do with this slimy mess? I mean, this is for my dick to pound!!! This is not for my face to get involved in. My tongue belongs in her mouth and my dick belongs in her pussy. This is inherently wrong, ass-backwards!!!"
But I had to start it and after about five minutes, I got the hang of it. Next thing I knew, my horny girlfriend was fucking my face, my nose, lips, tongue, forehead, chin and I was like OMG, I didn't know that a female had this kind of drive, being brought up in a male chauvinist society. I actually thought that sexual pleasure was in the domain of the male and she was just basically a sex object.
It opened up a whole new world of giving her pleasure and enjoying her excitement. But, like smoking your first cigarette and gagging and taking your first swig of scotch and having it burn your throat, licking pussy for me was an acquired taste. But once acquiring it, it certainly became addictive.
