so i got my first full size dildo

[LateBloomer]

when i say full size i mean the size of the a little bit bigger than the size of the average(5-6)penis. the feeling i get when i start inserting is a burn feeling. i doesnt hurt like its to big, but it is to uncomfortable for me to keep pulling it in and out. i thought maybe the lube im using is trash(astroglide), but really i have no clue. any help plz

Try loosening yourself up with just a finger or two first. Go slow and relax. You might have to actually "bear down" in order to relax the muscles down there (as if you were trying to gently pass gas). Lots of lube is good.

Also I find real penises are easier to take than rigid dildos. Depending on what the material is, you might as well be using a baseball bat.

Hope some of that is helpful.
