I agree that sex is easy...so easy that even a congenital idiot can do it (manage the basics, I mean)...but what's hard about talking?There are some people who are hard to talk with, of course...is that what you mean? This is usually because they don't really see talking as a cooperative or a mutual activity, but rather as a war. (My father comes to mind...)
On the other hand, there are a lot of people one might be quite happy to talk to, but not want to have sex with. I can think of thousands of people like that with no difficulty at all. Almost everyone I know, in fact.
Therefore, I would suggest that sex is a more specific matter than talking, and a matter involving more discrimination (in the positive sense of the word).
There are some subjects that are hard to broach...but there are some sex acts that are likewise hard to contemplate. Well, for me, anyway...
I recall, for instance, a sexual position on this zodiac calendar I saw that I believe very few people could manage were they not members of the Hungarian Olympic gymnastic team.
This is indeed a subject that has many ramifications, and I'm sure with a little work we can stretch the discussion of it out almost indefinitely.
William Shatner finds either sex or talking about equally easy, by the way...
