Is it necessary to have a DTR conversation?

My friend and I were arguing about this. He said you should always DTR when you're sure you both like each other, but I'm like why ruin something that's working?

Do you have a DTR conversation with someone you want to have a relationship with? If so, who do you believe is the person responsible for initiating it and when?
Yes
No
