How do you have a girlfriend/boyfriend?

I've never had one before (And most likely never will), but I'm very curious as to HOW one has one.

I've been reading up on the concept for years and it sounds incredibly overwhelming. All the studies/research papers I've read show them as tremendously exhausting.

#1. How do you determine the proper contact frequency? Does contact have to be made every 12, 16, or 24 hours?

#2. Who initiates the contact first and how is this decided?

#3. How long should each date/outing last? What is the accepted standard?

#4. I know that calling is no longer appropriate for relationships where both parties are under 30, but does the same protocol apply to other forms of communication? (Email, Snapchats, and voice messages)

#5. When asking somebody to be your girlfriend/boyfriend for the first time, what phrase works best and ensures the highest success?

#6. And most importantly, how do you maintain power in said relationship? Every study I've read says the person who lacks power is always the weaker member, how do you prevent this?

Thank you for reading!
