Frustrated

It's peak time to BD and hubby can't get it up. Happened last month, too. I'm almost 39 ttc first child. He is 45. Doc won't prescribe meds cause if high blood pressure. Extra frustrating because DH won't follow through on lifestyle changes to help the situation ie lose weight, quit smoking. Process is hard enough without adding erection problems. Annoying. Afraid we will miss our chance
