Had first 3way with wife earlier this year, thought of her looking and wanting others cocks is a turn on to us both.

no its hot not weird i love emn ogling my wife

Never with wife but years ago had good sex with another couple and talked about it later. We both liked watching each other enjoying and being enjoyed by another

My ex-wife loved my cock. She loved sucking it and playing with it all the time. She loved watching me jack off and loved watching porn with me or even just watching me jacking off to other women in porn magazines and videos. I started buying her Playgirl Magazine while I was out picking up all of my favorite girly magazines for the month. She would thumb through them when I brought them in to her and never really look at them after that. I did this about 3 months in a row and she was just never into looking at them, although there were a couple of male porn stars she kind of enjoyed watching, but I stopped buying her Playgirls once I came home from work and she was masturbating to the women in my magazines. She did confess to me one time about having fantasies of sucking the dick of one of my best friends.
I have had a few girlfriends who admitted they liked looking at other guys dicks and some would share their fantasies and/or experiences with me.

Not weird - there's all sorts of kinks and that's (one of) yours. It's all good.
