My girlfriend and I sometimes enjoy phone sex every now and then while being away from each other. I know it seems nerdy and weird to some. However, in efforts to turn her on sometimes, I find myself saying things that happen to turn myself on more. For instance, the other night, I thought of an idea for her to start talking about her with another girl. She is not bi-sexual, and she got displeased with the idea after the second night of trying it.
Basically, my question to you all is, is it all that wrong to fantasize about things of this nature? And is it wrong for me to tell her that I like that idea?
Thanks for all your answers, and help. It's greatly appreciated.
