[How To Fit A Big Anal Toy]

Ok, so i have a dildo that i would like to use for some anal fun,

the problem is, its got a fairly blunt tip on it and its about 2-2.5 inches in diamater and i can't get it in there

i feel like trying to force it in is a bad idea,

i've got plenty of lube

is there any trick to getting some massive girth into yourself or how to loosen up a bit?
