Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Do not opt for fake advertisements claiming capsules and tablets for penile strength , prolonging sex & making patients fool . Certain molecules which are having results are also not without side effects some of which are very serious as chest pain , heart rate disturbances or else ; so without consultation of urologist , not advisable to consume . Provide enough time in foreplay , after play . Consume plenty of liquids . Balanced nutritious diet intake with enough iron , vitamins , minerals , proteins . Regular walking in fresh air , exercises , relaxation techniques , YOGA help great in creating self confidence . Avoid stress , anxiety . Manage to have regular sound sleep of 8 hours . Cut off use of mobile , internet in bedroom . Discuss with the partner regarding her likes and dislikes with love . Keep your blood sugar , cholesterol levels , body weight under control . Avoid smoking , alcohol if consuming . Consider sex as an art rather than just act of finishing ejaculation . Plan sudden surprises as uninformed leave from job coming home , candle light dinner , surprise gift , outing , variations in sex acts which matters a lot. Hope I have answered your query. Let me know if I can assist you further.
