My girlfriend and I have wanted to up our anal game and try pegging for awhile now, but in my search for the perfect dildo I continually encountered one of two obstacles: the dildos I found were either a) lengthy and girthy enough to be very, very daunting, or b) slim and manageable but completely cylindrical/textureless, which is useful for someone completely unused to anal penetration and still learning how to relax, but that someone isn't me.
This dildo is the best of both worlds--it is slim enough that it can be inserted with only a small amount of warmup, and it has a fantastic beaded texture that heightens sensation with penetration. The beads are well-graded, distinct enough that they can be felt but not so pronounced/individualized that they cause involuntary clenching. The subtle curve results in some very pleasant anterior pressure when inserted, and while I wouldn't say this dildo specifically targets the prostate, it certainly presses in all the right places. I am (and have been) very satisfied with this toy and would certainly recommend it to someone who is looking for manageably-sized options without losing out on texture.
A final parting note: this dildo is made of fairly firm silicone, which is not a bad thing by any means (and aids in sensation when inserted), but it does mean it has very little give. If considering this dildo as an anal first-timer, I would recommend investing in some progressive plugs that end on a size slightly larger than the one inch diameter of this dildo. Accommodating a toy at rest, like a plug, is very different from accommodating a toy in motion, like a dildo being used to penetrate, so stretching larger than the toy you are going to be penetrated by--especially if said toy is firm--is very important.
