Well,yes I have and the reaons are many BUT! just as some ladies can fake their orgasms a guy can also.The way to "fake " one is simple .By the word fake does not mean that you unload into your partner,Yes... she should know you are cumming .BUT! if you go into the same theactrics as a woman does you can fake it.
In my case I wanted her to have a long sexual trip,So I knew I had to prolong my self. So after several minutes of thrusting and grunting I proceeded to tell her I was about to cum and she urged me on. I kept my pounding into her till I pulled almost out and declared that i had cum then thrust it deep and flexed my cock like I had exploded in reality I had not. After kissing her she was very happy.I said "Baby I want more should I clean you out ?" Something we never had done before.
"OH! she cried as I went down on her and sucked her till she groaned then I proceeded to tongue her till she came again.BY this time my cock was still hard which was my intent .She reached down and said "Oh! you are hard again" "Yes I replied you do that to me tonight" "Oh! she said again i wantto suck you and she proceeded to do just that after a bit I stopped her and told her I wanted to ride her pussy some more and mounted her again all in all it was a grand experiment.
