Again it depends. I CAN do any gender pairing. Whether i will is a different story. I mainly stick to mxf though because people apparently can't RP fxf mxm.
Also I like to kick it off starting as an action/adventure or something. I never make the romance the main part at first. I also don't do love at first sight. Mainly I pick fantasy settings preferably medieval or on a made up world. With a made up world there can be moder parts and medieval parts to kinda allow for character differences and yadda yadda.
Also I'm not a dramallama. I don't do drama romance or teenagers. Or vampire romance unless you have one hell of a vampire. I prefer adult characters even if the content is PG. Which I would prefer. I'm not one to enjoy getting banned.
