This is kinda related and you might want to check the studies mentioned in this article:
"High blood pressure is a major cause of erection problems. A study in the Journal of the American Geriatrics Society found that about 49% of men ages 40 to 79 with high blood pressure had erectile dysfunction.A more recent study of men with high blood pressure, published in the Journal of Urology in 2000, found that 68% of them had some degree of erectile dysfunction. For 45% of the men, it was considered severe.High blood pressure keeps the arteries that carry blood into the penis from dilating the way they’re supposed to. It also makes the smooth muscle in the penis lose its ability to relax. As a result, not enough blood flows into the penis to make it erect."
I’m not sure about flaccid size?
