I am. Told my GF before she moved in with me, back in the 80's before we got married and had kids. I married the horniest girl I ever met. I always knew she would like fucking others. Surprised it took us so long to try it. surprised there isn't a section in the forum page here got guys like me who are bi, but not cucked. Sure I love to see her well used, but I am very much an active participant when we host others. Love to put on a show for our guests. I am not a sub, I do not wear panties. I love when one of our str8 guests laps my wife's juice from my shaft while he pounds her. Would love to hear from other horny masculine Dads who share wife/gf, and are bi, or curious.
