Is it normal that i not only cum without having an orgasm, but my jizz is cold?

For the last five or six times in a row, I have shot without actually orgasming. I don't masturbate all that often (maybe 2-3 times a week) and I at least try to build myself up. Additionally, my jizz almost always comes out cold rather than warm. It's not the air cooling it, because I can feel the coldness as soon as it lands on my stomach. I'm not sure if I should be concerned or if this is more common than I think. Thanks in advance
