Things only big dicks can do

Make my partner wince and struggle as the sex starts up. It has always began with my partner sitting still, just getting used to the size for a minute. One past partner used to insist that I remain perfectly still at the beginning - not even the slightest thrust allowed.
 
What are things only big dicks can do, and not average/small dicks like jerking with two hands. It doesn't have to related to sex.

Open doors......

and bang on them !
 
Just saying this from experience, penetrating a woman's vagina while facing her standing up. Or kneeling on a floor or bed and doing it like that. Not sure how big you have to be in order to be able to do this, but if you are big enough to do it, it's highly intimate to hold your lover and hug them and kiss them while engaged in coitus like this ;)
