21M with ED issues, even w/ taking tadalafil

Hi,

I’m a 21M who’s been having erectile dysfunction issues since I became sexually active two years ago. For context, I don’t watch porn (occasionally maybe once a month I will but rarely and i still have ED on months I don’t), I lift weights and run 3-4x a week, overall seem pretty healthy.

I even started taking tadalafil 2.5 mg a day as of a couple months ago, and up till a couple weeks ago it had been working wonders. Now, I’m having trouble getting hard every session with my girlfriend and even getting soft in the morning. I still actively take tadalafil and am not sure what the issue is.

I’m sure it could be psychological, but given that I’m still on medication and am an active person I really don’t know what to do.

I also take creatine, magnesium, Vitamin C, D, and Ashwagandha supplements
