I think any "toy" is a good reliever. It's not always possible to have sex, but sometimes the desire comes at an awkward time. And, of course, when your partner is away, it's also difficult. At least you're not doing what many others are doing, and that's cheating on their partner with another lover! You just have deep, unfulfilled sexual desires that need to be met every now and then. Besides, I don't think a toy will ever replace the real thing, it can't offer you the human relationship/emotional part since it's a dead object, so don't worry about that.

I'll be honest OK, I'm a guy, never had a girlfriend, and I've considered buying one of those fake vaginas already. I also feel like I would have to hide it and it would be embarrassing if someone found it. But, if they do, I'm going to leave a little note attached saying "Well, what did you expect? I'm a guy, I have needs, I could never get the real thing, and my hands weren't good enough anymore."
