So confused!

I can't believe I am doing this...but here it goes. I have been married for 11 years. We have had a fulfilling sex life and we get along great. Things went bad a year and a half ago or so and I had a bad feeling in my gut. I snooped and found that he had been sexting with someone on Facebook. Stuff hit the fan and we decided to go to counseling. Through counseling it has now come out that he has "curiosities". He wants to know what it's like in a 3-some with another girl. As if that's not awkward enough, he also wants to know what it would be like with a man. He says it's just a "parts" thing. He is not attracted to men and does not want a relationship with them...just wants to know what sex with a man would be like. I cannot participate in sex of this nature...it's just not who I am. I am being told by him and our counselor that this is super common with men...so guys...I am asking for you honest opinion...and gals too. What do I do??? Do I turn the other cheek and let him explore outside of our marriage? How would our marriage survive that?? Is this a common fantasy among men?? I have no one I can talk to about this. It's not something you bring up to your gal pals over coffee and certainly not to your mom!! Help :)

Yes, a lot of men retain their adolescent experimental phase of wanting to try new sexual things. Real men, those who are not still boys in their heads, look for love and commitment before sex. Your husband is still emotionally immature. You shouldn't have to compromise your values and beliefs for him. Tell him to find a sex teacher and you move on to look for a real man. They are out there and this time you will know a bit more about what to look for. Keep your self-esteem and pride and leave this boy to do his growing up on his own.
