Has she explained why she doesn't like anal anymore?

I don't know about the dynamics of your relationship so maybe you guys have talked about this before. I really hope that when you suggested that, that you already knew she'd be okay with or interested in seeing other people.((considering eden is pretty sexually diverse I'd hope you have, but its one of those things I'm not comfortable assuming, especially in these cases.)) If not then "You don't give me anal, so I'll get it somewhere else" wouldn't be an appropriate response at all. If she doesn't want to do something sexual for you she doesn't really have to, and suggesting that you both just have sex with other people because of it could maybe be devastating. You'd be okay with it all but I just hope you made sure she's okay with it, as her feelings are important too.

But if you've already properly talked with her before about what I mentioned above, then I just share the question of dv8: has she mentioned why she doesn't seem comfortable with anal anymore? Or have you asked her about it before?

There's more to the story! 3 years ago I found text going back and forth with a guy who sent her a dick pic and her response was "mmm yummy, I can't wait to see it up close. Last year I read some FB messages where she was setting up to meet someone at a hotel. I know she really enjoys anal sex, I'm afraid that someone else is blowing his load in her ass.

Oh dear-- that would happen to be cheating unless if you guys have clearly agreed to an open relationship. If you're entirely fine with all that then I guess just talk to her about seeing other people.
If not then maybe the issue is deeper than just anal and more about trust issues and deception? I can't tell you for sure since I don't live your life or know you*, but either way you'll have to talk with her about any concerns you have. Communication and all that

*Sorry by the way, I don't mean to come off as aggressive, or acting as if I know the full story. The most I can do is ask questions and offer my thoughts/opinion on the matter since that's part of what the forums is about.

No need for apologies, I thank you for your honest response.

Personally I've always said if a guy was going to be in a relationship with me even if we hadn't engaged in more than kissing yet he had to be willing to commit to being with only me for the duration of our relationship. There is no way I would ever share my husband. It has nothing to do with trust or security, just I don't believe in sharing partners. That being said finding the texts and messages would have been a definite issue if it were my relationship. Did finding those things bother you then or have you always liked the idea of an open relationship? I'm also curious as to what the point in marriage is if you're willing to share your partner? Not trying to be rude here, just genuinely confused. It is possible that she is letting another guy into her ass, but it's also possible that she's no longer nearly as into it as she used to be. Maybe something even happened with one of the other guys involving anal that has left her uncomfortable with having anal sex. I'd suggest you talk to her about why she no longer wants to have anal sex with you. Just question her gently about it and pay attention to her response (both verbally and body language). The issue may be a lot deeper than you think.

omg, feel so bad for you. Hope things turn around for you. Just be glad you didn't catch any diseases.

Oh no. I feel for you. I know exactly how that feels. Hubby came every time we did it but he went through a "no" phase too. I was quite hurt and had to just go it on my own. Talking about it seems to have helped him see how much it means to me so he's considering it again.
