For the gay male of the species, a big dick is generally difficult to deal with for various reasons. (If the afore-mentioned gay male does not have a big dick, then there are three basic ways to play, with almost infinite variation.) First is manual stimulation (jacking off). Having a partner with a big dick is often a nice thing in this sense, in that you can usually get both your hands around your partner's manmeat, and have a lot of fun. Second is oral stimulation (going down, blowjobs). Needless to say, if you try to go down too far, a big dick can choke you or even make you gag. Third is anal sex (buttfucking). A big dick can, almost literally, tear you a new asshole.
Of course, if the gay male is used to fisting (well, more specifically, being fisted), he can receive anal sex from someone with a big dick without too much difficulty -- just use a lot of lube.
