As long as I can remember throughout my childhood & well into adolesence, long before I could possibly understand the full implications of sexuality I have had a fascination for genitalia. I suppose you could say that I technically lost my virginity at the age of about 4, when I was playing with the kids across the road & when we would rub our penises together. One of the kids had a sister who wanted to join in, who would sho us her 'penis' by squeezing it, when it would pop out (something I learned in much later years to be the clitoris), so in order for her to join in the game I pushed mine into hers for a few seconds. I may have got a thrill from it, but not so much one of a sexual nature, as I had no idea at that time that such things existed. Even from those early days, right the way through puberty the boys would always be comparing each other and then, once the body entered sexual maturity we would often have group masturbation sessions together.
Why would you assume that licking armpits or pubes has anything to do with a fucking ass? Did I miss something in your logic or did you?
It doesn't matter to me. It ultimately is up to each person, so if my partner prefers one way over another, then I'm cool with that. It would actually be pretty neat if she would switch things around from time to time, too. That way you get to experience it all, from full bush to shaved clean, and everything in between. I however expect her to have the same kind of laid back view on this subject as my own. I like to avoid conflicts especially over something trivial like that. I myself trim from time to time since I'm not circumcised and some strands could get under the foreskin if they are really long. It's uncomfortable when that happens. But at the same time it's not the end of the world either.
