I see the question has been reworded after my initial reply so here it goes again.
If the question is would I enjoy sex with a man without any ejaculate then the answer is sure, why not? As long as he is able to orgasm then I don’t care if he makes goo or not.
If the question assumes a man doesn’t orgasm without ejaculate then that’s false, sorry. I’ve had a few lovers who had been able to have more than one orgasm before the final orgasm with ejaculate.
Again I’m going to write that a man being able to ejaculate has little to do with how long he’s interested in foreplay or his stamina during penetration. I’ve had lovers who can get an erection after orgasm in less than an hour and some who needed nearly the whole day, surprisingly to me their ages didn’t dictate this.
My personal preference is for a man to be able to have sex with me and have his own orgasms each time twice a day on average and the goo doesn’t bother me a bit.
