Talk to Urologist on Sexology, Andrology

My penis size is decreasing it used to 2.5 inches flaccid few months ago now its come down to 1.3 inches Few days ago i forcefully pulled outwards and since then i have been feeling mild irritation under the skin and the flaccid size decreased further to about 1.2 inches. i have lost almost an inch in few months. i have good libido and facial hairs too. m having alot stress. it used to pull inwards n then when i would manually pull it outwards. but from the few month when i pull out it wouldnt be possible like the shaft is stuck in itself and cause pain for which i would take pain killers and voila after few days i would have a smaller size and a weaker erection as well weaker nocturnal p tumescence.erection usually would return to normal but the size would remain smaller, same happened few days back. i had normal size and erection on the first day but suddenly on the second day i had a weaker erection and smaller size.
