I am 53 year old, have regular interest in sex but since a year or more I have erection problem and premature ejaculation. I am regularly taking losartan-h for high bp and my bp is under control and normally be 128/80. I often take 03 peg liquor (whisky) at night. Please advice, should I take tadalafil and dapoxitinne tablets or some other drug, and its dose. Thank you.
