hi i have been together with my current gf for about half a year. everything is going great but i have trouble getting and keeping good strong erections. i think it is damaging her confidence a bit. she asked me up front if i have some sort of erectile dysfunction. i asked my doc and he says its probably due to stress etc. i just dont want her to leave me because of my erection difficulties. we both love each other a lot. i have started taking some supplements to help with issue (l-arginine, etc), we'll see if that works. is this something women would leave men over? how can i explain to her its not her at all? dont want to lose her and shouldnt be having these problems. im in my mid twenties btw. thanks.
