Actually, I would argue that the most important history question for a male HTN patient is "Have you ever had any bouts of severe chest pain that you couldn't explain?"
Erectile dysfunction won't kill you, but an MI might.
Actually, the reason why you "might" need to know if the patient has erectile dysfunction is to see if he's already on Viagra. Viagra causes the blood vessels to dilate, and may lower your blood pressure. If you're on Viagra, and then add a medication that lowers blood pressure, then you might get
hypotensive, which can sometimes be as dangerous.
As far as I am aware, the first line drugs generally prescribed for HTN (i.e. lasix and metoprolol) do
NOT usually cause ED. HTN, by itself, can contribute to ED, but the medications usually do not.
You don't really need a heart rate or a respiratory rate, to be honest. A respiratory rate of 12 vs. 16 doesn't tell you much (and when you do inpatient medicine,
every patient seems to have a respiratory rate of 18, awake or asleep).
And a heart rate of 88 definitely doesn't merit a beta blocker.
I wasn't suggesting that you shouldn't ask about MI's. We should ask about PMH, FH, and any current symptoms of MI's. It's clearly something that must be asked in the history. No doubt about that. The reason I brought it up was because it is a common issue and cause of significant morbidity (and easy to remedy, ... we have great ED drugs). Asking about previous MI's is not something that is commonly forgotten.
Most HTN drugs, including the ones you listed, can cause ED:

It's almost impossible to predict if a given HTN med will work for a given patient. There are some correlations by race, etc., but it's a trial and error process at the end of the day. Recommendations are to start with a diuretic (plus others depending on the patient) but many physicians don't start with a diuretic.
The thing to keep in mind here is that the number of men on antihypertensives and diuretics is huge. Between "2005–2006, 29% of all U.S. adults 18 years and older were hypertensive (systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg or taking medications for hypertension) (CDC data). ... Overall, 68% of adults with hypertension were using anti-hypertensive medication. ...The prevalence of hypertension was nearly equal between men and women." So if ~29% of men are hypertensive, ~68% are on hypertensive meds and we have 300 million Americans (and let's say half are men), then we have ~30 million men taking antihypertensives. Thus, even if a small percentage of men were non-compliant with the HTN med due to medication side effect (ED, etc.) the effect would be huge. I personally know of a handful of patients who required surgery or presented with CHF after they chose not to take their HTN meds due to ED, and I'm just starting my experience with patients.
Here is one article that illustrates the problem. Obviously I'm open to better stats & studies if anyone has some:

Abstract:
Erectile dysfunction (ED) can lead to treatment noncompliance in patients taking medications for chronic health conditions. Using the Intelligent Health Repository, NDCHealth's longitudinal, United States health care claims database, we examined the impact of treating ED on adherence to long-term therapies in previously nonadherent patients. Male patients >=18 years of age were identified who received antidepressant (AD), antihypertensive (AH), oral hypoglycemic (OHG), or lipid-lowering (LL) agents and initiated therapy with sildenafil citrate (Viagra) between January and June 2003. Treatment adherence was determined using medication possession ratios (MPRs) for the 12 months before and after the first prescription of sildenafil. Prior to initiation of therapy for ED with sildenafil, 64% of patients with comorbid medications were not adherent (MPR <0.8). Among these patients, 728 (27%) received AD, 2112 (78%) received AH, 984 (18%) received OHG, and 1078 (40%) received LL agents, with 66% of patients receiving multiple therapeutic classes. During the 12-month period after the first sildenafil prescription, patients had a significant increase in medication adherence compared with the 12 months before the first prescription of sildenafil (P < 0.0001). The percentage of patients who became adherent (MPR >=0.8) with medications after sildenafil treatment was from 22% to 36%. With the exception of the LL group, there was a significant relationship between >=3 sildenafil prescriptions and change in MPR (P < 0.05). Patients aged >=65 years had similar improvement in MPR as patients <=65 years. Treatment of ED with sildenafil improved adherence in patients taking common long-term medications who were previously nonadherent.

Based on this article (again, I'm open to better stats), ~29% of patients were non-adherent prior to ED meds. 29% of 30 million is about 9 million American men that might not be compliant with their HTN meds if it wasn't for ED meds. If if the number is 3% or .3%, we are still talking about a lot of mortality and morbidity.
I wouldn't fault you for not worrying about a heart rate of 88 because it isn't listed as one of the "official" CAD risk factors. However, there is some indication that it could be a risk factor for CAD and that makes sense to me. Also there is data to support the use of beta blockers in certain patients as well.:

Abstract
Aims: Heart rate reduction is the cornerstone of the treatment of angina. The purpose of this study was to explore the prognostic value of heart rate in patients with stable coronary artery disease (CAD). Methods and results: We assessed the relationship between resting heart rate at baseline and cardiovascular mortality/morbidity, while adjusting for risk factors. A total of 24 913 patients with suspected or proven CAD from the Coronary Artery Surgery Study registry were studied for a median follow-up of 14.7 years. All-cause and cardiovascular mortality and cardiovascular rehospitalizations were increased with increasing heart rate (P < 0.0001). Patients with resting heart rate ≥83 bpm at baseline had a significantly higher risk for total mortality [hazard ratio (HR) = 1.32, CI 1.19-1.47, P < 0.0001] and cardiovascular mortality (HR = 1.31, CI 1.15-1.48, P < 0.0001) after adjustment for multiple clinical variables when compared with the reference group. When comparing patients with heart rates between 77-82 and ≥83 bpm with patients with a heart rate ≤62 bpm, the HR values for time to first cardiovascular rehospitalization were 1.11 and 1.14, respectively (P < 0.001 for both). Conclusion: Resting heart rate is a simple measurement with prognostic implications. High resting heart rate is a predictor for total and cardiovascular mortality independent of other risk factors in patients with CAD. © The European Society of Cardiology 2005. All rights reserved.
Again, heart rate is less of an issue and I could see why it might not be a factor at 88 for many (or even most) clinicians) in what antihypertensive meds they chose.
