Personally, I'd rather not, all it does is make my libido flare up which is quite annoying to someone who has a natural lack of interest in anyone in that way. I've tried it in the past but no matter how much I've tried to enjoy it, I'm still indifferent to it, it does nothing for me. As I have said before, the philosophy of sex is more interesting to me than actually performing the deed in any way myself, including masturbation.
So, as such, I'm much more content to not masturbate. I'm in a few ways of the opposite of opinions from those here, but for the same reasons. The libido flare-ups interfere and destabilize my own normal psychological health, and are more a case of irritation than of pleasure. Which is why I rather not masturbate at all.
