I've noticed you argue a lot with people trying to understand your questions lol. Since many of your questions make little sense, I would consider reviewing this policy. Not a criticism, just an observation...
As for your original question, it depends. So ask the woman you're with. I cannot emphasize this enough. You can get 100 answers from 100 women, it has nothing to do with the answer your woman would give, and that's the one that matters.
As for me, well, it depends. Personally I seem to have 2 different kinds, 1 from my clit and 1 from my gspot. They feel different, and they seem to happen differently. Personally I prefer the ones from my gspot, but again I guarantee everyone is different. And if you're asking is it the physical stimulation or the emotional connection, the answer, is yes (waiting for the confused response to that one...).
One final thought that I often feel is really overlooked, is that being with someone you're comfortable with can help the orgasmic process in more than 1 way. Yes the comfort, but also the familiarity with how I'm put together. This is why sex tends to get better with familiarity and I personally feel a guy's size really matters less in a longterm relationship. You just get to know each other so well that way and, for lack of a better way to put it, things that I may initially hope occur by accident, can begin to occur on purpose!
