really need help

Married. Regular married sex life. He started asking for different things and some of them I have done, but usually something that didn't make me get it. I think I neglected myself. Big error.

Now I can't get it at all, I need to orgasm really bad. Sometimes I get close but nothing. Am I the only one??? what do I do???

I have tried guiding him but same outcome. Tried myself, nope. I am avoiding a friends with benefits proposal that i got so doesn'tcountlike cheating. I need help.

Moves, ideas, something, anything.
