(Male) masturbation would feel better without orgasms.

When you're jerking it, it feels good. Edging feels good. After orgasm, you lose all of your arousal and get grossed out by whatever just turned you on. Not to mention the refractory period. And on a more serious note, you actually remember how hungry you are after you cum. Whereas I don't really feel any hunger while masturbating and thus don't have to take the time and effort to cook meals. Just drink lots of water.

Obviously it'd be bad to be aroused 24/7 because of 1) damage to your penis from priapism and 2) it's disgusting and creepy to be turned on around family and such. But if these problems didn't exist, I'd love to wear some kind of vibrating chastity cage that constantly keeps me on the edge of orgasm. Or a magical cock ring that allows me to feel pleasure but not orgasm. But alas, that's not possible, just like cold fusion and cloning dinosaurs isn't possible.

As a side note, masturbation feels a lot better when you're sleep-deprived because your whole body feels erogenous.
