As far as her losing interest after her orgasms.... Do you continue stimulating her after yours? You may be able to prolong her interest by engaging her after you've finished.
Marlboro and I tend to fuck ( or make love depending on our mood....) until I orgasm and then when he's close I suck him clean and swallow his cum. It's nice to know that he still wants me as an interactive partner after my distraction of an orgasm is over. I've always been a selfish lover, I've told my partners "After I cum, you have about 10 minutes to finish and say what you need to say or get your crap and get out because after that I'm going to sleep." It's only in the last few years that I've become interested in anything beyond my own orgasm.

Maybe see if you can help her rub out another orgasm after you're done so she doesn't feel that you're rushing to get hers out of the way so you don't feel guilty about getting yours and passing out.

As for the crying it may also be lamenting that she doesn't feel like a partner so much as a duty (see above). When I was with the Ex-sbian who shall not be named. I cried after sex with her because I felt obligated to sex i didn't want. I felt used because all I was for her was another sex toy. A way to get off without using her own hand.

It may be possible that you and she might do better to seek a marital counselor. Perhaps through your church or community center. Many people feel safer opening up in that environment. I would hold off on the suspicion of cheating until all other options are exhausted. Even I come home from work most mornings smelling of other mens colognes because many of the alternate shifts' men just HAVE to get their "Red hug" in the morning. ( Yeah apparently it's easier to call me by my hair color than to read my badge...... >shrug< )

Always,

Kyttn
