I have been watching porn and masturbating since 7 years sometimes I did heavily. I started it even when I was not matured. My penis was not that strong and never saw 90 degrees. Now my penis is almost flaccid all the time and when flaccid it's very small around 4-4.5 inches and very less girth but when erected (of course not stiff erection) it's 6-6.5 inches in length and 4-5 inches circumference. Nowadays even though I have feelings towards a girl it's not erecting but only when I see porn i'm getting a kind of erection but not strong and not 90 degrees however i'm able to masturbate. Penis also not experiencing much touch (sense) feel. I went through few tests like testosterone, fsh and lh tests, doctor said its normal. But growth of hair in my private parts, beard and armpits is a bit slow. Im getting erections when I watch porn but not standing for a long time. So is there any solution to my problem, if so what should I do. please let me know!
