Alpha BF

Hello! I don't even know if I'm supposed to be here, but I'm a woman and nothing turns me on more than strong man fucking a weaker male. My BF is a total alpha, he could easily fuck my pussy 3 times a day if I allowed it. I really want to bring a sub man for him to fuck, that's my biggest fantasy in life. But every time I mention it he immediately refuses. Do you think is there any way for maybe convincing him of using faggots for me to watch? Or should I just keep playing with my dildo while watching gay porn?
