hi, my age is 16 and i got an erection problem. my problem lately is that i dont get a morning wood anymore. and whenever i do get an erection its not like it used to be. like i used to get very hard erections and now my erection is weak. but i get an erection but only when i watch porn or sometimes randomly 1 or 2 times day. i used to get erections 3 4 or more times in a day. could it be because i watch porn too much or i masturbate too much or because of my lifestyle i dont exercise too much i am obese and i have high sugar. my doctor gave me an anti diabetic medicine sitagliptin+metformin HCL but still i have this erection problem. please help me, PS another thing is that i whenever i pee i does not flow easily like i have to push very hard only then it comes out and even then its dosent flow easily its a big strain and a little painful and semen comes out with urine too
