"My partner leaves me unsatisfied. What can I do?"
My partner gets everything he wants in the bedroom, but I am often left wanting. How do I switch this dynamic around to my benefit?
Open your mouth for starters. Does he know you're left 'wanting' or are you smiling sweetly and saying everything is fine? Men aren't mind-readers and if you're pretending to be satisfied, he's going to accept it at face value.
There's no need to confront him, just speak up. Say (sexily), 'It's my turn tonight - and I want you here first', meanwhile pushing his head south. It's both customary and polite these days for him to give you an orgasm before penetrative sex, given that it (finally) appears to have got through that most women have their orgasms through oral sex rather than intercourse.
If it's not just orgasms you're missing out on, again, you need to be more assertive. Work out what you'd like to happen in your next sex session then tell him what you'd like to try. Could be he takes control because you're passive and don't contribute.
If you're already suggesting stuff and he's ignoring you entirely, you're dealing with a completely different problem. He's sexually selfish. In my experience, selfishness doesn't confine itself to the bedroom so take a long look at your whole relationship. Could be he needs an ultimatum of sorts.
