Long gape between intercourse and regular masturbation under erotic influence (like pornography in your case) may lead to early ejaculation. I do not think drug prescribed to you will make any difference, as this problem is not related to hormone (Andriol is hormone). You should try Kegel’s exercise. (you may search Kegel’s exercise in search box).
Medicines like Fluoxetine and Clomipramine can also help.
