Frankly, if you do anything it becomes boring after a while (most couples who have had sex for many years will admit a monotony in it; if just a slight bit)
Places like jackinworld.com have a massive amount of info on different ways to masturbate; some of them aren't a bad alternative to sex toys/artificial vagina's.
Some techniques like the stop and go (building yourself up the point of orgasm and then backing off...doing this as many times as possible) makes it not only a game; but one hell of a good orgasm when it happens.
A limited amount of pornography may help boost things up (if you can, try to read sexual stories instead of just looking at pictures, it'll help you keep your sexual imagination and fantasies going better than any picture could give you..it will also help prevent you from losing your ability to become sexually aroused visually)
