Well, once again, I am finding it hard to add anything PoP didn't already cover! She's right, silicone is the way to go and you can try some dual density types which are the firm inner core ones with a softer outside. Or you can go for the regular solid silicone which is more firm, but depends on the manufacturer. I understand some are really expensive for someone experimenting to see what they like, but remember, these are toys that last a lifetime with proper care. You can sanitize them between uses or partners with no fear of transmitting anything. Pathogenic microbes cannot hide in this material after proper cleaning unlike porous materials! Let me say, I have the Outlaw by VixSkin and it has a squishy head while my Bandit by them is much firmer. It turns out there can be some variability depending on who hand poured the dildo, but these dildos are meant to be more realistic.

On this site, I searched for dildos only made of silicone and between 3.75" and 2" diameter and 2+" diameter. Here are the best ones and that PoP didn't already mention:

Here is one that's silicone, 2.5" diameter and 8.5" long: Musclehead

Here is one that's 2" diam by 8" Long: Mr. Seven

Here's a dual density one which might have too much squish for you, but you can read this [and you can red this review of it by PoP who answered above|review] of it by PoP who answered above: it's 2"diam by 9.5" Long Sumo

Here's 1.875" diam by 7.5" Long Captain

Here's 1.75"diam by 9" Long Python

Here's 1.75"diam by 9.25" Long Camelback

Here's 1/75 diam by 8"Long Mr. Smooth
