If you have time let's say, a few hours, sit on the loo (I like to do this anyway, so sit however you wish) and press as hard or as soft as you like on that famous Graphenberg spot for ages, and ages, and ages! Do it long enough and pee that feels like cream will spit out at your hand and sometimes your arm too.
If you have built up enough tension for long enough, over an hour at least, you may get massive orgasms which last for minutes at a time and they're countless, making you lose track of time. I don't know if people know when they are ovulating, but if orgasms are intense enough at that time and you keep forcing them out, eventually you might get a massive spray of gush from your uterus that feels runnier than syrup, more like water but more creamy consistency and it smells as strong as! Believe me it feels as if some pressure cooker has blown it's top and spilled water all over the place!
