hey /d/ me and my girlfriend tried anal yesterday. We have had both the same amount of anal masturabation experance but her ass is MUCH looser than mine, to the point where i couldnt stick my dick in, with little problem at all. while I'm as night as a fucking clam.

is there an explanation, and maybe methods for me to ease up my asshole?

i dont have any pics with anal, so i guess this will do?
