Ive had them just twice, both times with huge dildos in my bottom. As others have said, it takes quite a while with the right amount of pounding: not too hard, but for a long time.
There is the other, much more common type, where penis and anus orgasm at once. Those also are very strong, but not nearly as strong as the whole-body orgasms that can arise from anal fucking alone.
I read thru the responses to the question of achieving an anal orgasm. Your response was much the same as quite a few others claiming it takes a long time. My question is how long is a long time? Are you talking 15 minutes? An hour or more? Give me an idea of your definition of taking a long time. And, during this extended period are you constantly penetrating yourself, without a break? Yes, reasons I am asking is I have tried to achieve anal orgasms and never have. I have done so using my own anal toys as well as having my lady peg me, and she has begged me for what I feel is a long time, in the area of 30 plus minutes. Much appreciate any info you have!! Thanks!
Dont go anywhere near your penis, just think about your anus, you may think that it is not liking itself to be intruded but given time ( it doesnt need dildos ore any other fancy things) it will start to enjoy your fingering. Suddenly your anus will want your fingers and you will cum deep inside, while your penis will harden and ejeculate. You will cum in two places at once while only giving anal stimulation!
