I'm very bi-sexual but also very open to the interests and idea's of other people. A good buddy of mine who i served with in the military and currently work with at a prison here Nashville, Tn recently confided in me that him and his wife ocassionally place ads on some sites to invite others guys over to there home so that him and the other guy can compete to see which guy can make his wife have more orgasms. I was blown away but found it fascinating at the same time. Does anyone else know of couples that do this. Have any of you done this and how did things turn -out? Is this more common than some may think? Let me know of you guys expirence's with this if any.
