Without the feeling, sex loses most of its attraction, but yes, it's possible for men not to feel an ejaculation.
Very interesting question!
You may know something more about ejaculation.
Don’t overthink your goal. Ironically, if you try too hard to reach orgasm, you likely won’t be able to at all. When you are thinking “orgasm, orgasm, orgasm,” you can’t release and enjoy your partner’s touch. Instead, simply be in the moment, and don’t take sex so seriously. Have fun and just enjoy whatever feelings and pleasures come. When you have such a mind-set, you are more likely to reach orgasm…more than once!
Don’t let your arousal fall to zero. When you reach orgasm, it’s natural to want to take things down a notch (some women report that their clitoris is very sensitive following orgasm). Try to switch positions or put the focus back on a different activity, whether it’s oral sex, intercourse, or self-stimulation. But don’t let your arousal drop back down to zero, because it will be much harder to bring it back up. Instead, keep the embers lit. Keep thinking sexy thoughts and enjoying your partner’s touches and caresses. After a few moments, you will likely be ready for more intense stimulation and orgasm once again.
Let your body guide you. Multiple orgasms are probably not going to happen during every sex session, and sometimes you simply won’t have the time or energy to make orgasm a multiple occurrence. Listen to your body and let your arousal guide you. Don’t judge your orgasms or compare them with what you see on TV or what you hear from your friends — an orgasm is an orgasm is an orgasm, so enjoy them whenever and however they come, whether they happen once, twice, or thrice!
Make it a sexy game. Text your partner a naughty message like, “How many times can you make me reach orgasm tonight?” and then take turns bringing each other to new heights of pleasure. Remember, sex is ever evolving within a relationship, so by committing to exploration and keeping the communication lines open, you can ensure that your sex life never gets stale or predictable..
