Ah, another subbie with a buttplug...the world just became that much of a better place
I'll repeat for repeatedness: LUBE. Don't try to be heroic at first...lather the thing up and don't keep it in for long. We've found something oily -- KY or such -- works better than lotion, which tends to be squeezed out of where it needs to be. You want to find your limits (everyone responds to them a bit differently) and it's helpful to start with GOOD experiences, not freaky ones that make you want to quit.
As for getting them in, relaxation is key...if you can't relax, and so can't get it in, come back to it later - don't force it. Pushing ever so slightly out can help too -- not like you're trying to poo, more like you want to release a comfy no-one-else-is-around fart. If you'll pardon my crudity![]()
Enjoy, and do keep us posted...*cough*photodocumentary*Cough* hehe
