The trick is in the tail...

Is there such a thing as sex immunity in the same way as one gets porn immunity (thanks to DTG for pointing out that post)? The reason I ask is that I have begun to find it harder to cum unless we are indulging in some slightly aberrant act of sexual congress.

Me, cock deep in Mrs S's arse with her hands pinned over her head?
Fine - I'll be gurning like a loon in a few minutes.

BTW, why do men pull ridiculous faces when they cum?

Missionary with the lights out?
It isn't going to happen.

Don't get me wrong I enjoy it all. I remain priapic to the last. However, the orgasm is tough to come by, so to speak. So, have I become too anally obsessed, too desensitised to vanilla sex?

Well, not completely. I can still orgasm through quite normal sex - I did last night, for instance :-). It just takes some time. I guess that may be the reason that I have been coming more frequently in anal sex - by the time the wife is turned on enough to want it, I am close to the brink anyway. But what concerns me is that it's taking me longer to get to that "point of no return".

As an aside, on porn immunity, I'm not sure that the theory works completely. Yes, my tastes in pornography escalated to more and more hardcore stuff over the years but it has now hit a plateau (though some would say that its tough to find more digusting stuff than "Anal Sluts III"*, I am very sure it is possible...). Furthermore, I still find soft core images or even just perfectly innocent pictures of a beautiful woman very erotic (for example, Bliatz's gallery is more than enough to get me hot under the collar...). I can still easily stimulate my “mind clit” as Bliatz calls it.

What's the male eqivalent of the “mind clit”, by the way?
“Dickhead”, I suspect!

Enjoy...

* I made up that title, so if "Anal Sluts III" exists and happens to be so disgusting that merely perusing the cover art induces violent vomiting, then don't assume I watch it on a regular basis...
