well first off i would sugest that u go to the doctor, tell him that u are having trouble getting hard. if u have a cool doctor he will just give u something no questions asked. if u have a real doctor, he will test your free testosterone through a blood test. and if this is fine, u are screwed most likely. if not, not only can u get dick drugs but u can also get synthetic testosterone. win win. but…very unlikely due to your age.
so next step would be make good friends with a local drug dealer. haha
