An orgasm is hard to explain in words; you can feel or experience it, but it's hard to put into words. However, the best way to explain it is that when a person is having an orgasm, they may gasp, move uncontrollably, or feel like they are suspended. These are all nonverbal cues that let their partner know that they have had an orgasm. Most of the time, regular vaginal contractions and ejaculation happen at the same time in females. The person seems to be calm and happy later on. It doesn't take long to show that you've had an orgasm. To be sure, it's best to ask the Partner.
