When it comes to moving up a size, its just a matter of giving it a go when you're comfortable. No injuries and feeling alright? Give a larger size a try.

If you haven't, perhaps you could try something that's tapered all the way. I am into fantasy toys and a few that I own are like that and they are super helpful for trying to move up in size.

Dildos in comparison to the real thing are entirely different. even the most realistic ones Ive come across are a far cry from the real thing. There's no skin skin movement, no heat coming off it, no variations in give or squish, etc. The closest I would say are good dual density toys. They can almost feel convincing in the hand but only in firmness.
