I think I might have Erectile Dysfunction, I am 23

Hey everyone I was hoping for your opinion! So last week around Thursday I noticed that it was really hard to achieve anything past a half boner. I'm not in a relationship but I do play with myself daily (something I've always done since I've been like 13). As the days have progressed I don't believe my situation has gotten any better. However I can still somewhat play with myself and achieve orgasim. About myself, I'm in extremely good shape. I take good care of myself by exercising 6 out of 7 days a week. And I sure do try to eat the best diet also. I drink maybe once a week, I do not drink enough where alcohol would be the issue. I don't smoke. I am not on medication. I am not in a relationship so there could be no stress from that. I really do not think it could be any other health issues such as diabetes or heart disease considering ED is my only symptom. My thoughts, maybe this could be just overall stress? I know when I was a few Yeats younger I had a day or two stretch where I had trouble achieving an erection. Second thought is a day before I noticed my issue I started to get sick and am still sick... Could a cold or virus cause temporary ED? I'm trying my best not to stress out however my mind is going crazy because I am a young and healthy man so this should not be an issue for me... Thank you for listening any insight is appreciated.
