Um, your profile says you're a female but often these profiles aren't accurate. If you are female, some females do gush when they climax. I don't know statistically how many people do this, but it is natural for some women to do this. If you're a male, of course, male ejaculation spurts out, and the first thing that comes out is watery and then the sperm comes out and is whitish and sticky. I'm guessing from your description that you're female, as this sounds like a good and strong ejaculation some women have and if you have that it's just who you are. Orgasms don't always feel the same, and when we start having them they aren't necessarily as strong as they can get when we know better what turns us on. Some people have screaming shouting raving orgasms and some have quiet mild ones. We're different from one another.
Is this ejaculation? Are you climaxing?
