This is a great dildo for anal. This was my first dildo, and it was such a good experience that I've not only expanded my selection of toys to include vibes, dildos and strap ons, but I still use this one regularly.
The ribs can be very pleasant, although sometimes if I'm not in the mood, they can be a little much. Beginners should just warm up a bit and take it slow - it can be very rewarding. It's very soft and long. Perfect for anal and my gf likes it too.
The base suctions a bit, so you may be able to use it in the shower or off another surface if you'd like. It stays put, but doesn't perfectly suction to withstand too agressive of movement.
My gf and I have used it with our strap on harness too. It fits the harness well enough and stays put. She's been a little rough on me with it, and it's soft and pliable enough that it feels agressive but it doesn't hurt. It's fallic enough to fulfill some fantisies, but the colour makes it still unrealistic enough to be "safe" and not take these fantasies a little too far.
I love it, and I'd suggest any beginners who are interested to drop a few bucks to try it out.
