Would love to try out Twilight or Greys Anatomy if you're up for it :) 

After reading your description, we're basically in exactly the same boat. I'm 19 and female as well :P I can post multiple times a day, I'm a sucker for romance, been roleplaying for years so no worries about length or mary sues or anything of that sort :) And I'm okay with playing your OC's love interest. I can play either male or female, open to any gendered pairings, etc.
