You're right it is his lost. I can't imagine my spouse even thinking about another woman... hell, she doesn't even touch herself... I think you should take the next opportunity you have and make your fantasy a reality... you only live once and you have to live it to the fullest.... you don't have to let him know... even though I can't imagine him not wanting to know that his wife was with or even thinking about another woman... isn't that every man fantasy... well with him joining you.. have you ever brought that up to him, maybe that's the way you can have you first experience with another woman and then maybe things will progress from there...

If you do take on that adventure, take your camera... he, he, he!!!
