Hi I'm a 21 y.o male who has recently been diagnosed with heart disease and I have many things wrong with it Inc. A hole in my heart a missing valve and damaged valves and increased heart size due to these problems, I was just wondering wether this would have a effect on penis size as I seem to have a relatvly small penis when erect , or could this be due to the fact that I have not fully grown as I was late in pubity?!
