It's 'difficult' if you have a small dick, if the other guy has a small dick, if you are a sexually crippled frigid-cunt 'top' and if the 'guy' getting fucked is an emasculated dickless 'bottom', then I bet it's difficult. But if one is vers and hung, and the other two guys as well then DP is not only easy but super enjoyable.
