So called Hands-Free orgasm. Basically you are fucking your ass with a dildo until you cum... But I have problem. I cannot jerk off without incorporating hand in process. My cock stays soft. Can't get enough erection.. What should I change? Position? Hit G-Spot? Use plenty of Lube? Patience? Does it get better more you do it? Will you ass and prostate become more and more sensitive more you do it so you just orgasm with time? Its complicated. Hit it without stopping? Please I seek advice from expert that has achieved this. Its possible and I m serious about it. Those types of orgasm and anal mastrubation are mind blowing. Thanks.
