Dry,cant orgasm

So for some reason i cannot nut,at all. When i masturbate and play with my clit i orgasm but it takes a few minutes for my juices to come out. And that seems to be the only time i do nut. Im starting to think somethings wrong. Im too yound to have these problems especially too young for my vagina to be dry. Even when i get turned on i dont get that wet. And when im having sex when i get clise to an irgasm it just feels like a lot if pressure. Last time i almost shitted myselfbat least thats what it felt like and i tried to hold it in and the built up pressure made me burp instead. Idk if aur was being pumped in me but thats what it felt like. Idk,uts really wierd. What do i do? 😢
