Hey all, usually just lurk here for advice, but actually need some personal help. On a 42 day NoFap streak (19 Male) after not getting fully hard with a girl a couple months ago. The past couple of girls I've been with, I haven't been hard enough for vaginal intercourse, usually 50-70%. I don't know if it's a mental thing (not being stimulated or just nerves) wearing a condom (which kills stimulation), but it's really annoying. I'm working out, studying, etc. but the past couple of times with girls, it always just ends in a blowjob, which I can orgasm to. Anyway, I've read a lot about L-Arginine helping. Could y'all please provide suggestions/help? If L-Arginine is a solution, dosage and time to take would really help?

Let me know if you need any more information that may help and thanks!
