Hey, DD, we're still best buds. I had orgasms solo before I ever had sex, and I got off the first time I had sex (I count myself lucky), so I expect to get off. If I can get off this time with this guy, no reason not to get off that time with that guy.
It is the woman's responsibility to know how to get herself off and know what works. That comes first. Different women have different responses. The guy can't just guess where she likes pressure, and what intensity and rhythm and escalation. And those things differ from day to day.
But then if the guy gives a shit, and - here's your communication thing - the woman can speak up and not just give up, there should be orgasms for her, whether from oral or intercourse, by cock, hand or vibrator. The woman really has to take the attitude - it's not over 'til it's over. If she says a cuddle and kissing are bliss enough, that's her choice. It wouldn't be mine.
Truly, the woman at some point should be in the drivers seat, maybe on top, and the guy following her lead on pressure etc. The communication can be all physical, not vocal. I can do it from underneath as well. He's very responsive to a slight pressure on the small of his back, to tilt his pelvis for the right pressure in the right area. It's like driving. I slow down, he slows down. I tilt to find the right spot, he stays put. Or I tilt a little and press his back a little. I'm determining an up and down or circular grind, he's responding and reading me.
The only reason I'm putting this much detail is that I learn from talking to people in the chat room and stuff that a lot of people don't grind, they thrust. (Maybe they watch too much porn?) We thrust for 15 minutes or whatever, with some grinding thrown in liberally, but when it's time to come, I'm driving.
So I'm not putting the responsibility on the guy. But, really, if somebody is walking away all engorged without an orgasm, there are lots of diverse things to try. All of them pleasurable! What works for me is just an example.
