hi im 18. im not sure if this is
erectile problems. I remembered when i was
young, about 13, i would easily get an erection without much stimulation and i can also maintain it for a long time just with mental stimulation.
But, right now, i have troubling maintaining an erection without physical touching my penis or physical stimulation. i can maintain my erection only if i keep on physically stimulating my penis by rubbing it or "playing" with it
is that a health issue?
