Problems getting hard

So I am fairly new to gay sex (I came out a few years ago) and I have been trying to put myself out there and experience what I can. I used to use alcohol as a crutch to gain confidence to actually meet/go home with men, but I realized recently that I believe this is giving me ED, so I’ve decided to not try mixing sex and alcohol.Whenever I masturbate alone, I generally do not have a problem staying hard or feeling great. It’s when I’m with men that I cannot get/stay hard, though I believe this is due to the alcohol as stated.However, I hadn’t had a drink today and I go over to this guy’s apartment and try to have sex, and I am again finding it impossible to even get hard. Beforehand, we did a couple lines of coke, so I’m wondering if this compounded my problem as I start to get embarrassed about being unable to perform, what I hear is another cause of temporary ED.I am 24 years old and have a pretty good libido, so I’m not sure why this is happening to me. I have only been brought to orgasm with a man twice, and both times I stroked to completion. It is very worrying to me and I’m starting to wonder if I’ll ever have a healthy sex life.I’m not sure if it’s because I put too much pressure on myself in the bedroom and that gives me anxiety, causing me to not perform, or if it’s overindulgence in porn that’s dulled my ability to appreciate actual sex or that I use it as a tool, and without it, I’m impotent.Anyway, thanks for reading this. Please tell me what you think and how I could go about fixing this. Thanks gays, have a great day. :)
