to introduce my boyfriend to prostate/anal play, and boy did it open an ENTIRE new world for the both of us! I wasn't sure how he'd feel about it, but I bought a few more mainstream sex toys (typical vibrators, lubes, cock rings, etc.), and I sort of hid this one in with the rest. Wouldn't you know it was the FIRST one his eyes went to. This is a perfect toy to introduce your man to prostate play. It's easy enough to insert (smaller than most plugs you see out there), and is really ergonomic so it feels comfortable/pleasurable once inserted. We never get sick of using this. It's also great because he can wear it comfortably during PinV sex - the handles on either end don't get in the way, but give him extra sensation.
I really like the "syn" series from Aneros. I started with the MGX in just the white plastic and it was great but there are definite improvements with the silicone versions. The "tails" are more flexible and more comfortable against my body. The silicone is smooth slightly more forgiving than the plastic. This Eupho is a bit more advanced but it works for me! Feels great and hits the right spots hands free!
