Get some lube to make the dildo a bit slippery, and then gently push it in. Once it's comfortable, then you can decide what else to do with it.
force it
as big as someone makes one
If they were big, they couldn't fit out of the vagina at birth.
As big as you can take it
It can be any size that proves usable and fun. Too small ones wouldn't be effective, too large ones wouldn't fit in.
This all depends on the brand and what type of insert you want. If you have a small fireplace with a simple insert, its not difficult. But if you have big fireplace with a heavy insert, you should let an expert install it.
It depend's if she has a small and thin or big and thick vagina. If it's small and thin, you can only fit 1. But if its big and thick you can get in up to three. ;)
Some Can Be Very Small And Some Can Be Alittle Alittle Big

A BIG dildo
you shouldn't be too worried. masturbating should be the best it can for a girl and if your girlfriend buys a big dildo, it means she is looking for maximun pleasure. but no dildo can replace the touch of a person == I should say so. You need to ask her why she needs it if your relationship is good. Maybe you can use it with her to give her better pleasure. Maybe you don't measure up to her needs.
