Manually manipulating the Eupho Trident

You should be fine if you aren’t ramming it. The rule of “don’t press your prostate harder than you would your eye” seems to be pretty good. Anyways, hard direct pressures can numb sensation. If you want to explore further than aneros toys provide and in a directional manner, try a wand (njoy, for example) or a flanged dildo. I have a silicone dildo with an adjustable interior structure that allows for direct massage, and that goes in 6 inches (way more than I use). Just don’t be tempted to cut off one or both arms of an aneros toy, just to get it in further!

If you can live without the K-tab, cutting it off will certainly give you an extra quarter inch at least.

Just cut it about 1/2 an inch from the junction, and sand down the rough edge of the stub. I have done this with all my tridents, as the K-tab does nothing for me, and hits the bed when on my back. I also appreciate the extra penetration.

I feel like if I could get just an extra 1/4 inch on my Eupho it would be perfect.
Any advice for me?  I currently own the Trident versions of the Eupho, Helix, Progasm, and Jr.

If you grind down and sand the stem as shown in the left side copy of this image you should easily get an extra 1/4" of penetration. However, you may also lose some stability but gain more mobility/agility with this modification. With the slightly deeper penetration you may then want to adjust the P-tab/K-tab arms as well but I'd suggest not doing that until you've had a few sessions with the reshaped stem alone. I did this mod to my original Helix and it worked quite well

Good Vibes to You!
