A sex marathon between two persons doesn't require "rules" - you just enjoy eachother for as long as you can, taking breaks as required.

Not rules but suggestions. If condoms are involved, use polyurethane. At a microscopic level latex is quite abrasive and polyiso is a synthetic latex and not as smooth as the polyurethane. Believe me it makes a difference if you go through a couple dozen in a weekend. As in, you cannot sit comfortably for a few days.

Use plenty of lube whether or not you think it is needed. Pudenda do not wear out but can be quite sensitive to short term overuse.

When having sex for a long period of time, sexual fluids and sweat are likely to build up and then dry, irritating those areas where they've dried. It is a good idea to rinse off every once in awhile. Also, if you haven't rinsed off yet, you can often just add a dab of water to reactivate the lube instead of slopping on more(though that is sometimes called for). Keep a couple bottles of water and some light snacks handy. It's better to consume small amounts throughout than to wait until you're thirsty and drink a lot. If you have been having sex for a while, then multiple orgasms are probably likely and the mind is already primed for pleasure and the body should be relaxed so this would probably be a great time to explore lots of other forms of stimulation and regions of the body. As to what qualifies - who cares?! It's not a competition to compare vs others. Do whatever the two of you want for as long as you enjoy it.

Condom considerations also exist for the male during extended sessions if he has considerable girth because simply wearing a tight condom for a long time can grow painful. If this is the case, polyisoprene is less irritating for the man than polyurethane because it is stretchier. Unfortunately there are no non-latex condoms for larger girth at the moment. You could also consider a female condom, though I do not know how well that would work for extended sessions on her end.

I am curious what the proper guidelines would be for the correct reapplication(or not) of spermicide during marathons since the amount of fluids each woman produces along with the amount of lube used and consistency of each would vary the drainage of it.

The 'accepted practice' during marathon sex is to take care of any issues during breaks. Doing so right from the start prevents big problems later on so I encourage both genders to "go to their separate corners" in between 'bouts' and tidy up. You then join back together for the re-hydration and teasing before the next round.

You reapply everything as if it were the first time this evening.

one idea, have one session be a shower or bath to tidy each other up, kill 2 birds with one stone
