My GF 21F says that I 19M need to try woman older than her.

My GF has been for a while fantasizing about me fucking people around and older than her, to the point where she would even share her friend's bikini/private pictures with me and asks me to get off to them(they're fine with it). I would like to surprise her with a few other girls if possible that are interested, you can even be younger than her its not such a big deal. Tell me what you think
