Hi. Thanks for your query. Noted your history of being 50 years of age and have a problem of premature ejaculation which you feel is due to excessive masturbation. Since this is the only history and you have already consulted and got treatment from a Sexologist, he must have gone through all the other history, investigations, actual examination and then only gave you the treatment of (1) Bonafide forte (2) Ignitor (3) Ig Tg Forte (4) Paternia XT (5) Depoxetine Tablet (6) Lyconergy V.. All these are safe medicines with minor side effects and if they occur you can definitely consult back to your treating Doctor. I think these should help you. So do not worry about the side effects. The time taken for cure of your problem can be a few weeks to few months depending upon the cause and the actions of the medicines on your body. Premature ejaculation is usually due to stress and mostly anxiety and medical problems like diabetes, hypertension, alcohol, tobacco and so on. Hence is it needed to find out these problems too.
