That is one of life's great challenges, my friend. Some woman orgasm easily, others not so much. A provider who is very comfortable with her own sexuality probably finds it easier. There are endless websites describing the signs of a woman's orgasm. There are women who, for various reasons, can and do convincingly fake an orgasm. I once had a provider clamp her legs shut as she almost thrashed off the bed and nearly ripped my ears off after a long session of slow kissing and DATY: so I'm pretty sure that one was real. Then she gave me my money back and asked me to marry her. OK, that last part didn't happen.
The key, in my experience, is to make the experience not just about your own pleasure. Approach having sex with a provider just as you would with any woman. Communicate and establish some connection with her if you can, talk with her and treat her like a lady. Be slow and gentle to begin, put her needs ahead of your own and then listen to her, pay attention to how her body reacts to the experience, and follow her lead. Granted, it is not always easy to do this with a complete stranger while the clock is ticking in a typical session. But it's not that hard to give it your best shot, really.If you pay close attention, you can feel must less friction in the way you stroke her as she orgasms. Nipples do become taught butt that doesn't always mean she came. The squeeze is a dead giveaway though. A woman tends to squeeze her pussy walls together to enjoy and enhance the orgasm. I'm not saying it happens for every woman the same. I agree that a woman has to have reached a comfort level with her own sexuality to have more control and enjoyment, but it's no different than the way men have to learn to find their rhythm and prolong their erections.
I'll bet a few of you remember this commercial jingle.
My provider's orgasm seems real. She has a big smile on her face and she DFK's me after I unload inside her BBFSCIP.
