Orgasms??? (I know again)

Okay. When ever someone asks this question "how do you know when you've had an orgasm?" Everyone replies with "you'll know" or something along those lines. But I and many others didn't/don't know. Porn builds it up like every girl is supposed to have something come out or squirt when having an orgasm. But that's not the case. If you want to add more such as; "what an orgasm is", "what your first orgasm felt like" or "this is what will happen when you have an orgasm" please do. It could really help someone out. Thank you girlies 😘💕💜
