Got a problem again. My kids are asleep, our bedroom door is locked and we are enjoying teasing and stripping etc.we are getting hotter and hotter and she is humping me but I am not doing any penetration just teasing. I am hard as a rock, a little fellatio some serious blow then we are ready for some serious fucking. I start to mount and I am like the Pillsbury dough boy!!!! She is going crazy for it and I cannot get it hard enough to penetrate?? She tries all she can to get me back up but I cannot perform. I had taken 40 mg of Cialis cause I knew it was going to be a night of adventure and just continuous sex but then nothing. Do you think all the exercising and stretching, pumping has caused me to get desensitized? I finally got her satisfied using other ways but I was so frustrated and could never get off. Any suggestions of reasons will help me get thorough this new problem. I don't always get to have these long nights of fulfilling my sexual fantasies where she is ready to try anything that I want and then I can't even stay hard! I am so frustrated what good is 7+ inches is it does not get there. I have only gained 1/4" in 5 months and have not stopped exercising daily, but a few times. I eat healthy, not over weigh, do not watch adult entertainment, and rarely masturbate ( my wife keeps me satisfied when ever I want it) don't know what to do. Thanks for listening to my rambling, depressing night.
