Hmmm... I haven't written much for LGBT roleplays either, but I'm also willing to give it a go. Would the roleplay be entirely centered around the romance, or are there other things going on, too?
PS: Welcome to Iwaku, newbie! If you fill out your Roleplay Resume (click your avatar at the top of the screen and then Preferences) it helps people check quickly whether or not their writing style would mesh with yours, and therefore helps you find partners faster!
