What Can I Do To Regain Erections After Discontinuing Masturbation More Than A Decade Back??

I masturbate prone for years on daily basis up to three times. I don t even know that a boy can have morning erection due to early masturbation. But I have stopped anything concerning masturbation since 2011. Up till now am yet to get erection. I don t know whether the base of my penis has been affected. Am hungry for sex but no erection.am 43 years now.what will I do to get my erection back.thanks.
