TL;DR at bottom

My parents have always been strict about movies. When I was younger than thirteen I wasn’t allowed to watch PG-13, only PG or G. The same went for R rated movies - almost entirely forbidden until my 17th birthday. I’ve loved movies that that are a little too gory/inappropriate for PG-13 for as long as I can remember, and from fourteen onwards I begged to see different R rated movies. I was always turned down. Now that I’m older, and have actually seen those movies, I totally understand my parent’s reasoning. What I don’t understand is how they’re treating my younger brother. 

My brother is around fourteen, and doesn’t really show the same interest in these types of movies. Of course, that might be because he’s watching them already; it seems like everyone forgot the rule as soon as it didn’t apply to me.  I don’t know if it’s just the curse of being first-born, but it irritates me like nothing else.

After a lot of complaints my parents are starting to see my perspective, but now I’m stuck with a hard choice. Apparently I, my dad, and my brother might all go see Deadpool 2 in theaters. But only if I agree. I loved Deadpool, but it was one of the movies I spent a long time begging to watch in the past. When I was fourteen I could hardly imagine seeing it, and my brother’s being handed the opportunity on a silver platter. I’m half-tempted to knock that platter right out of his hands. 

My first reaction is to keep him from seeing it just because I wouldn't have been able to, WIBTA if I did?

TL;DR: I couldn’t watch R rated movies until I was 17, now I get to choose if my 14 year old brother can see one, WIBTA if I said no?

saying I don't want my brother to see an r rated movie
