can you tell from where did you learnt those exercises. coz i've seen some free penis enlargement exercises are really dangreous to perform. I am doing these for 1-yr and i've never experienced any problems.

Its' normal that you have little erectile dysfunction, bruises in which case you should leave it. Always do exercises which are professional, and reviewed by doctors, even if payed.
as for current problem, if they are professional then they should guide you. otherwise you should stop doing exercises and meet your doctor immediately.
