===Sustaining Sex===
Sustaining sex requires a [[Constitution]] check. Sex between creatures of different sizes gets more challenging the bigger the difference between partners is. For example, a pixie (a 2.5 ft. small fey) and a mature storm giant (a 21 ft. huge giant) attempting to have sex will suffer a -12 penalty due to being 3 size categories apart. While barely a problem for the giant character due to racial bonus to Constitution, a pixie is likely to fail any checks with her average score of 11 Con. Some solutions to this predicament are:

*Focus on Constitution during character generation. It’s not necessary to put your highest roll there - a score of 14 or 15 points will already make you quite a trooper.
*The Endurance feat provides a +4 synergy bonus. (Which already makes it better than the "vanilla" Endurance feat by miles.)
*The Sexual Training feat offers a +2 Constitution bonus for the purpose of sustaining sex.
*As usual, spellcasters come to the rescue. An ''invigorate'' spell offers a +4 bonus to Constitution and grants you Endurance feat for its duration. However, while powerful enough, as per the 3.5 standard, to make entire other class builds moot, it is ''also'', in an unusual show of restraint, level 8 Druid magic, so it's best not to rely on its availability. It can be substituted with a wondrous item, a 6,000 gp acorn crafted by a dryad. Which still isn’t something to be relied upon, since, despite being massive sluts, dryads aren’t a listed playable race in the ''Book of Erotic Fantasy'', but one can argue they'll be trading the ''shit'' out of these things if the real world is any indicator. Remember that birth-control herb the Romans literally ate out of existence?
*Osquin Root, a pretty dangerous drug, increases your Con for the purpose of sustaining sex by 1d8 points. Eating it more than once per 24 hours can render you permanently sterile.
*Having 5 or more ranks in Perform (Sexual Techniques) provides a +2 synergy bonus.
*Your partner having 5 or more ranks in Perform (Sexual Techniques) provides a +2 synergy bonus as well. You can benefit from up to two partners with Perform (Sexual Techniques) in this way. So, if sex with one giant seems troublesome, try having another one join in! Three or more partners provide no additional benefit, but they don't get in the way as per rules, either, so might as well have as many as you can, since attempting to have sex more than once within 24 hours carries a further penalty to Con checks.

With some of the above bonuses and 18 Con, a pixie can pass the DC 10 check and enjoy successfully fucking two Krakens (gargantuan creatures, -16 penalty) for 20 minutes, provided that they both have their Perform skill! (you can replace the Kraken's Diplomacy +7 with it, since, let's face it, a 100 ft. long squid is hardly the best ambassador, even with its 21 Int and 20 Cha). And if any or all of the participants took a couple of feats and/or are spellcasters with the right spells? ''That'' is when shit starts to get ''freak-ay''...
