Depends on whether or not you are looking for a realistic one or no? And size? What's your size and shape prefs & that'd be more helpful to give you suggestions.

I don't do the realistic dildos, or large sizes. In your other thread like this, I mentioned my top favorite toys for thrusting, which were Tender Touch Spiral, Lia G Bliss and Sweet Lola. Sweet Lola is glass with a bulbous tip. Not large though. Lia G Bliss is fairly petite too & has a slight g-spot curve. Tender Touch Spiral is straight & maybe around average size. It kinda tapers near the base.

All of those besides Lola have vibrations. I don't know if these are any that fit your preferences or not, but I adore them for thrusting! I mentioned what each of those toys do for me stimulation-wise in your last thread like this, so maybe that'll be helpful if any of these are some you're interested in.

Now, there's also Tantus toys, which are amazing for thrusting & they come in all different sizes, shapes and textures. Personally, I think the small Purr would be a huge hit for me since I love ribbed texture, flexible silicone and thrusting deep. It seems to be that the Tantus dildos would be perfect options for cervical stimulation, so if you're looking for something to be able to thrust deep with, I'd go with one of those.
