NO dependency and/or tolerance??

l arginine and pycnogenol taken together at the right doses for a month to two months creates more NO in your blood stream. I took it for a month and didnt notice much difference in erection quality except when I took them together then immediately got an erection after and notice it looked a bit bigger. Is it possible to build a tolerance or dependency on this? I was thinking of taking it again later in the year when I'm getting intercourse for just over a month but I don't want to risk becoming dependent on it or my body some how building a tolerance or lowering its own natural production even after I'm off of it (i.e, dependency). Can someone here fill me in on this subject?
