I think I suddenly have ED? What to do?

Not sure if this is the right place to post because I've been divorced for a year now. But it does have to do with sex! So here goes nothing... After months of not dating and being intimate with a woman, it finally happened Sat night. I've met a wonderful girl and we've been dating the last several weeks. So Sat night, it happened and I struggled keeping "up" and did not climax. Ouch. I will admit we had been drinking and I've noticed that it had affected my performance "ability to keep hard" before in my last relationship. The following morning I didn't have as much trouble staying firm, but I still couldn't climax. However, I was still able to make her reach a great orgasm. But I'm still a bit ashamed! I don't want her thinking I'm terrible at sex, cause I'm not. Could it have been the fact that I still may have had some alcohol in my system and lack of sleep? I've also been wondering if it's "in my head"? This is a possibility. But I've had a bit of an epiphany, just before I started dating again that I do not want reconciliation with my EX. That was a big relief actually. I just turned 41 years old. I am in great physical shape. Eat right. Exercise regularly as well as masterbate regularly (haha). It's strange. My first GF after divorce I had zero problems performing. My 2nd GF I struggled at first(not able to stay hard for very long and unable to climax), but then it got better. Now after my first time struggling with my 3rd, I am a bit worried. And she wants me using protection. I agree it's the safe way to go and will use it. But I am not used to using one at all and I could barely feel anything! So is this NORMAL? What should I do?? Should I get Viagra? Haha. I never thought I would say that because all my life I always craved sex, masterbation and climaxing always came easy to me, like nearly every night. I really like her and she really likes me. I wonder what she's thinking of me right now. I don't want this to be the one thing that becomes a deal breaker for her if this continues to be an issue.:mad:
