Hi! 
I wonder if you are still looking? 
I am older, too. I am looking for a 1x1 modern fantasy roleplay. I'm not great with world building (I usually take the rules of an existing world and adapt them to my wishes) but I have no problem, coming up with plots. 
I don't write seks scenes of any kind, and I love character development and building up relationships between the characters, romantic or platonic.
