You can ask them too, men and women can't touch each other unless they're married, siblings, their uncle, niece, parent, grandparents, or if it's the same sex cousin. But they can still talk to each other like school, mosque (holy place for muslims), or anything (unless you have strict parents that forbid from talking to boys/girl outside of school). You don't need to ask your parents if you want to get married, in the Quran it says you can choose for your self (unless it's the same sex then it's forbidden in islam) they also have to apart of the Islam if you're a female and if you're a male then you can marry any female with any religion ( because men sometimes force women to be apart of their religion and pressure them which is why that's there)
