Re: you did it for other men, but not me?
Likes change over time. And things you're willing to try may not be things you want to continue doing after experiencing them, if you don't care for them - especially things from long ago.
If it were something she liked doing within the last year or so with someone else, but won't with me, then perhaps there's an issue. Is it about me, or about her - or was it about him?
On the other hand, what if she liked anal, but you find it disgusting? Are you obligated to indulge her, or not? I'd say no, and likewise, she has the right to say no. You don't have to like it, but your options are to accept it, try to persuade her to try it again, deny her something she wants (childish), or break up with her.
Love is an ideal thing; marriage is a real thing; a confusion of the real with the ideal never goes unpunished. - Johann Wolfgang von Goethe
