A player whos new to Mutants and masterminds wanting to do a game

The title says for itself,i'm looking for a M&M game and i won't be the one DMing it since well,i don't have as much experience in it. I don't mind what the DM does,it could be sexual,dark,stressful,it'll be their call. i only have a couple of rules for who wants to be DM. rule 1: Don't be a jerk...no one likes the Jerk DM,if i did a stupid thing,i know i'll be punished by someone,but if i take precautions to make sure i did nothing wrong and it suceeds,don't screw me or the other players over for no reason. and rule 2: keep it familiar,as i said,i don't have a lot of experience,so i'd like a familiar setting at least,we don't have to be in the same timeframe(or timeline) as the heros of that universe,but just a familiar location and world is all i ask.

and a third little rule i forgot to mention,respect a players limits. there are certain things some people are not just comfortable with,like for example,you get a plan for my character,i'd like to know so i can offer my input on it. it may sound stupid,but i hate when people get plans for my characters that can mess it up entirely. like if my characters insane,and you have a plan to remove his insanity,i'd like to offer my input as a player to say 'hey,that sounds good' or 'don't go through with it,it removes a part of the character'. sorry,got a bit off topic,but yeah,some players don't mind things like gore,descriptive injuries,etc. but some players cannot handle gore or certain themes or ideas,it's just human nature.
