Re: Orgasm in sleep - that happens to me quite often. Sometimes a few times a week, once twice in one night (!), other times I'll go a few weeks without. They are, quite franky, the best possible orgasm possible. They are the most amazing, intense, unbelievable long and delightful ones you could possibly ever have.
They are of course g-spot orgasms (even though there is no stimulation - almost brain orgasms) but they are the same "type" as a g-spot orgasm.
I learned in my mid twenties to have a g-spot one without any clitoral help. They take longer to achieve but they are amazing and worth it. Nothing wrong with a clit/g-spot combined which are easiest to achieve. Not saying a clit only one is to be sniffed at but for me they lack "depth" - its like mono instead of stereo. (During sleep no hands one is like surround sound!)
If anyone has trouble achieving orgasm during penetrative sex and tends to do finger stuff and clit-only orgasms before or after, but wants to experience a clit+gspot orgasm, I highly recommend you experiment and perhaps invest in a g-spot vibrator or buzzing ball type jobby which you insert. You dont have to "do" anything else unusual except put it there and then do your normal finger stuff - but I promise the orgasm will be different than without. Once you really get used to that and really get the hang, you could try getting yourself worked up into an absolute frenzy one night, even if you have to do this alone and use some erotic literature or write out your most unbelievable sexual fantasy then read it back to yourself a few times whilst doing it - and dont do anything with your clit, just your chosen g-spot stimulator, and see if you can get there with just that. Once you have learned to do that, and indulge in that a few times, even if it is without your partner (though ideally include him! - but do it without him rather than not do it at all, if you are curios) you will find that your ability to orgasm during bog standard penetrative sex increases considerably. Its like your brain "learns" how to do it and it becomes really rather easy.
Hope that's helped someone, its probably a bit too saucy and TMI for AIBU and I probably should have name changed really as it will probably make me cringe one day particularly if someone recognises me from real life and decides to advance search me or something (!) but sod it, if it helps just one person achieve something new and wonderful then its worth it!
