I need external and internal stimulation, so I don't generally orgasm from either just a vibrator or just a dildo. but the two together are magic.

I believe that this would give you both external and internal stimulation because of the clitoral texture and the vibrations on the bulb and clitorally

I have always had a difficult time reaching orgasm and until the past couple of years (I'm in my mid-30's) I almost always needed a vibrator to cum. The Feeldoe more has surprised me in that not only is it amazing with a partner, but allows me to reach orgasm through masturbation, wearing the pony end and manipulating the shaft with movements like a guy jerking off (and I don't even use the vibrating bullet). Since everyone's anatomy is unique, I'm sure this is not the case for all. But, for me, it hits just the right places with just the right pressure and usually results in soaking the sheets.

I haven't used it enough as the wearer, with a partner, to find out if I can reach orgasm that way, though. I do know that friction against a lovers pubic bone tends to offer the clitoral stimulation I need.
One thought....if you are wearing it with a harness (like the Spareparts Joque that I have), you could use a butt plug too, which may offer the additional sensations you need to get off. I know the Feeldoe can be used anally, but that's something I've yet to try,
