...it is thought that what happens is that the male injects his sperm packages into the female's arms. The process is likely to be a fairly violent affair as the female is probably not that keen on being injected. This is a problem for the amorous male as females are normally a third bigger than they are.
"But males get round their inferior size by being endowed with a particularly long penis, which means they can inject the female without having to get too close to her chomping beak. The male's sexual organ is actually a bit like a high-pressure fire hose and is normally nearly as long as his body - excluding legs and head.
I thought that may get your interest. Quoted from here where, as a footnote to his post, PZ Meyers adds, “Forget March of the Penguins. There's a great documentary waiting to be made here: Squid Gone Wild. Cephalopod Sex Party." although strictly speaking he is referring to giant squid and not octopus...I wonder if he has similar fanatasies to me?… "I’m jealous of the multi-tasking tendriled/ tentacled, polymorphous orgasm-inducing powers of a series of fictional plants, aliens and cephalopod or gastropod molluscs!"...taken from the 2nd of Owsblog’s orgasm posts. 
Orgies always seem to involve images of wild gatherings including excessive drinking and promiscuity or of secret cults of ancient Greek or Roman deities with singing, dancing and drinking and often rites of sexual activity - early and tribal cultures had some group sex rituals associated with fertility and spring but these are not especially well-documented. In fact not until Greek and Roman Empires that a common word for those rituals emerged - orgia, in both Latin and Greek. Although many believe that the Greeks and Romans were sex-crazed, their orgia were not what we imagine when the word "orgy" is used, although ‘those’ - you know the ones I mean - orgies did occur. The original orgies were associated with the Greek cults of Orpheus and Dionysus, a pair that literally invoke wine, women and song!
The Latin orgia usually referred to beanos and feasts where gluttonous eating and binge drinking would be the norm; the guests at the orgia would often adjourn to another room with each other or with sex slaves provided by the host.
'Officially' an Orgy is any act of immoderate indulgence and may not necessarily involve sex (see Great Wall Party from China Daily) but more usually does involve overt sex, see Dutch story here...
...where 10 couples who were being "particularly boisterous" with each other while the others watched.
…But police called to the scene admitted they were powerless to act [Ows adds - just not turned on then? Ahem] despite numerous complaints from other beach users, and could only give the naked orgy lovers a verbal warning.”
Peety, were you involved!...;-)
Anyway getting back to cephalopods, orgasms and orgies I thought it a good excuse to add one or two more erotic illustrations from Marjorie Baldwin Greene (did you notice?) who's archives and sketches are well worth a visit. The one below is called 'Tongue'...
Am I normal or am I kidding myself when I think that I am?
S.O.
Now, whinging Englishmen is a cliche, isn't it?...but then we had the England v Ireland game that COULD have been a tournament decider...but with the dodgy try decisions in that game (I shall say NO MORE...grrrrr)...it was just as well it wasn't but they did win the triple crown - (image below)..anyway...whinge over, back to the binge; we were about 50 English, French, Irish, Welsh, Scots but mainly Spanish and even a few Portuguese...and we had a wail of a time, all good natured; it's only now I'm fully sober that I feel whingy!...so the obvious cure would be...;-)
