 [ Symptoms ] my 15 year old daughter has tricuspid valve regurgitation nausea getting worse [ Disease ] if a beta blocker is associated with ed i would suggest switching to a different blood pressure medication rather than turning to a medication to treat the ed fortunately there are lots of alternatives that are not generally associated with ed side effects like diuretics ace inhibitors and others what beta blocker or bp medicine will not cause ed abnormalities in blood pressure often relate to the diet and the body is ability or inability to absorb nutrients from food to deal with that problem i suggest you read about the gaps diet and dr natasha mcbride there is a powerful interview with dr mercola here <link> as for your erectile dysfunction problem it is common to lose your erection at times   especially under stress the fastest way to lose an erection is to start worrying about your penis and how long you are going to last allow yourself to enjoy the feelings in your penis as you squeeze it at the base this is the natural way to attain an erection then focus on how arousing your woman is and how much she turns you on if you are not attracted to your woman a different focusing strategy is required
