There are many problems with your reasoning in this post. You are ignoring the fact that men ejaculate from their penis when they come and women do not ejaculate from their clitoris's. Liking or not being bothered by the taste of semen is a personal preference for an acquired adult taste along the lines of liking the smell of musk on a sexual partner or the taste of whiskey. If I were a man, I would want a sexual partner who didn't mind the taste of semen because I prefer a sexual partner who is sensually into and open about all the aspects of sex and the human body, but I wouldn't take it as a personal affront if someone wasn't. (okay,okay I used to take this kind of thing as a personal affront, but I don't anymore ) Everyone has their limits in this regard. For instance, some people like to urinate on their sexual partners. That would be way past my limit and I'm sure yours too.
There are variations in preferences among high drive people too. For instance, I prefer being f*cked to getting head, so when I give my H head to the point of orgasm, which I do quite frequently, I am being sexually generous because I enjoy giving him pleasure. I'm not concerned about some tit for tat exact exchange in any given encounter. You say that you don't particularly enjoy vaginal sex, but is it in you to simply f*ck a woman good and well for the reward of her pleasure and the affirmation of a job well done?
