the first time i ever came that way i was laying on my back with my knees bent to my chest and spread as wide as possible and my EXgirlfried at the time had her whole foot in me all the way to the heal and was being very rough and hard with her movments and i shot all over my stomach without even realizing fluid came out till i looked but it felt better than ever before not long after that we split because the only sex i wanted was of course her penetrating me with everything possible then i told her i wanted a sex change lol i dont know why i even tried being with women i know i am only wasting my time unless its just for sex and fetish purposes
a WELL lubed middle finger to start. once you get it figured out where it is and how you like it, move along to a vibe. it's really hard to get at on your own, you need a friend so you can relax and enjoy yourself, maybe give some orders.
it is VERY difficult for me to find my prostate/stimulate it. last night my finger touched every place as far as it could up my ass...and still nothing. there was on spot that was sorta like a bulge, but when i stroked it i just got a very uncomfortable urge to piss & dispose of my feces...and even when i ignored that and kept going, after a long time i just gave up since it didn't feel that great. I would REALLY like to get this "prolonged orgasm" by myself...theres a small chance i'll be able to find someone to help
you may want to try a thin, flexible vibrator with a slight vibration to it. that vibration will likely help you find it just right. and even if you never get it JUST RIGHT it doesn't matter.
That would have to be one hell of a friend. Honestly I'd have to do it in front of a stranger because it would be too awkward. Hott idea tho.
ANSWER TO ALL THE ABOVE: Go to the STORE and grab a prostate stimulator, lube it, insert it and relax, allow it to work your prostate hands free. Done right, you'll have the most amazing hands free orgasm ever.
I don't have such a problem. Yesterday alone I came twice by this method. Ofc the butt plug takes the most credits but still...
