Since you take so many medications, odds are you will be in the future, too. Best way to handle this is: next time you meet with your doctor(s) point out to them your concern and also that erectile function is very important to you. The way it is working now, they are primarily concerned about treating the conditions you have, which is their job of course and are not taking erectile function into consideration because you have not brought that up.
Unless you say that 1) you suspect some medication is causing erectile problems and/or 2) you want erectile function to be a priority in your future treatments - eg, no drugs that will interact with others you are taking in some negative sexual way, they will continue on the present course of treating only pulmonary or GI issues. Knowing that this is a priority of yours will key them into paying attention to that as well.
Some years ago I became mildly hypertensive. My doctor at the time knew that I was sexually active and had no problems there so why would he worry about that? But what he prescribed as anti-hypertensive drugs eventually did have a negative effect. Had I then the good sense I do now I’d have mentioned at the start that I wanted no sexually negative drugs unless they were absolutely necessary to my overall health. At the time I took these drugs there were many options of others which would have controlled my blood pressure and not interferred with erectile function down the road. My bad for not expressing what are priorities for me.
