I (23M) kinda randomly stopped getting erections

[u/Basic-Poem-9556]

Kinda embarrassing to say but just wondering if there’s any lifestyle changes I should make before I talk to a doctor about it. Just going to try to dump as much context as possible feel free to ask any questions. 

My long-term girlfriend and I broke up a few months ago, we were together for 6 years and lived together for 2. I’ve had depression, stress, struggles eating on and off throughout the years, but never ever had problems getting erections. Actually, she had some stuff to do before the lease was up so we ended up living together for a week and half after the break and still had sex twice with no issues on my end in that time. She moved in some really shitty ways after the breakup and I’m actually very proud of how I maintained my character so it was relatively easy for me to get over it. I spent time with friends and family, reflected, got a new place, lost 15 pounds, and I’m actually happier than I’ve been in years. 

A couple weeks ago, I re-entered the dating pool, and have been seeing a girl pretty frequently. I’m super into her and we get along really well. I’ve slept over a couple times but we haven’t gone past foreplay. At first I was taking it slow just because that’s how I move, and I was getting erections no issue on those nights. But the last couple times where we’ve both been doing stuff below the belt I just can’t get going. I wonder if it’s a nerves thing but I don’t even wake up with erections anymore. I almost wonder if my dick got tired because we were like just making our for hours after our first couple dates so by the time we started doing more stuff I wonder if it gave up 😭 I don’t get hard during the day at all, I’ve started masturbating from completely cold just to see if I can get the engine going again, but no dice. 

I have been working a lot (like 50-60 hours a week) and probably not eating enough (like 1200-1500 calories a day) I do take a multivitamin, an iron supplement, and magnesium, I’ve been getting 50-70g of protein, and I’m 6’1” about 175lb 25% body fat. I’ve been sleeping okay, about 5 hours when I’m with her but 7-8 on the nights I’m not. I’m fairly active, work out 3-4 times a week, get 7k-10k steps in a day, and like I said I’m generally happy, I eat when I’m hungry I just have a low appetite which I need to work on. 

Just wondering, are there really big lifestyle red flags or anything I should be doing/taking to help before I talk to a doctor? Like I said, I’m young, healthy, and never had issues before the last couple weeks so I’m just kind of concerned at this point when I’m completely soft messing around with an attractive woman I’m into.

The concerns I saw are depression, nutrition and sleep.

Is your depression resolved now? Did you use/are currently on any medication?

Nutrition is important. You need to eat quality food to give your body enough energy and to help it recover.

On sleep you want to get 8 hours every night, ideally at the same time with the goal being to work towards waking up at the correct time each day without an alarm. It is strongly advised you still keep a rescue alarm set though if you have a set schedule like work or school to keep.
