Best girthy silicone dildos with a large bulbous head

Top pick: the AYIYUN 8.6-inch silicone dildo. It's the closest thing here to what you described — a genuinely thick shaft with a rounded, pronounced head, a suction-cup base for hands-free use, and silicone rather than jelly or TPE. If you want maximum girth, that's the one to start with.

Who the others suit:

• AYIYUN 6.3-inch — same thick-headed shape in a shorter, easier-to-handle length; good if the 8.6 feels like a lot.
• Mixers Lime Rickey 8" — a curved G-spot shape with a defined head; better for angle than for sheer bulk.
• Romp Dizi 7" — a softer, more tapered profile; a gentler step up in size.
• Adam & Eve Whimsy / Bliss — liquid silicone with a wide, rounded tip; the most forgiving of the thick ones.

One caveat: none of these list an exact head diameter, so judge the head from the photos and check the shaft width before buying. The Glas 12" is girthy but glass, not silicone, so I left it out.
