Yes, any man can learn to orgasm without ejaculation, and with a partner, including during "conventional" sex. Kegel exercises work for men as well as women, and "cooling down" is fine on your own, but what you really want is to refer to any good source on Tantric sex, and learn to control ejaculation with your mind. The first time you spend four hours with a woman in a variety of positions, without ejaculating once, you'll be glad you did.

On the other hand, some women don't properly appreciate this talent, because they refuse to believe it's not their fault you haven't "finished". Rather silly of them to think you'd keep going that long if you weren't enjoying it, but there you are.
