Yep, I always rinse mine under hot tap water before use, warms nicely. There are a few issues with Cyberskin in that it requires special care and is porous so make sure to use a condom on any Cyberskin dildo or vibrator. Also, store in a plastic bag with cornstarch to keep that skin-like feel, otherwise it will get tacky feeling after a while.
I really wish that a dildo could feel as good as a real cock, but I don't think that would ever be possible. How can an inanimate object replicate the feeling of a living organ pumping inside of your body? If it's the only option then it will just have to do.
Okay, I realize the following is going to sound like an ad for Silicone dildos, but since I am currently partnerless I'm getting daily use out of my sex toys which are dear and near to my heart so I feel like I can make a recommendation.
Again, the best is 100% Silicone, it holds heat nicely, has the highest material safety rating (non-porous so no place for germs to hide, and no harmful gases leaking out) and I find the Silicone to be more stiff than Cyberskin, but still somewhat flexible.
100% Silicone can also be placed in boiling water for up to 3 minutes to kill any bacteria - this applies to the regular Silicone or the Vixskin brand Silicone dildos (not vibrators).
100% Silicone is more expensive but well worth the price.
A great online store is EdenFantasys.com They have video product reviews as well as user-submitted reviews that are very helpful and the site lists accurate dimensions on each product page. Edensfantasys.com will also accept returns if you make a purchase and decide it's not what you were expecting - assuming it has not been used of course. Few places would allow returns.
Once you've identified a dildo that you want to buy you might want to cross-shop the price at SheVibe.com as that store has discounted prices.
Here's a link to one that I have that is a really nice size (8.5" insertable length x 2" or 6.25" circumference:
Vixen Outlaw Vixskin Realistic Dildo
They also have a wide variety of smaller versions if you think your girl would find this one too large. I can offer some suggestions for different models if needed.
Also, I recommend using Maximus lubricant on Silicone dildos.
Happy shopping!
