Been dating this amazing girl for 5 months now. In the beginning, we had alot of sex and the sex was great but now for some reason I can’t get up. I’ll be honest, I did used to watch porn and fap daily but I stopped doing that. This has been happening since June and Im getting concerned because I’m only 21 and feel like this shouldn’t be happening. I’m still in love with her and I still get boners randomly and when I think abt her so it’s not ED I think. Like there’s been times I’ve tried to avoid sex because I know my penis wouldn’t go up. Anyone know what I can do to prevent this? I’ve heard abt horny goat weed and drinking watermelon juice but I want someone who went thru this to lmk what I can do.
