Food restriction causing ED?

I got into bottoming because I enjoyed stroking myself while using toys in my ass. I want to be a "plays with myself while getting fucked" bottom not a "don't touch my dick" bottom.

But whenever I was with men I couldn't get hard, or if I did it was just a semi and super fleeting. I wasn't sure if it was just nerves or what.

I've also been cutting calories to lose weight the entire time I've been bottoming. I'm also super serious about being clean so I try not to eat too much before I know I'm gonna get fucked. Between the two I'm usually pretty hungry while I'm getting laid.

The other night after getting fucked I ate a meal with a top then went to bed with him rather than just leaving after.

After 20 minutes of cuddling and other stuff I had my first erection ever when playing with a man. We were both excited. He tried to fuck me but it was a little too much and also I felt nervous about bowel movements feeling food in me while getting fucked. But I still ended up making myself cum while he fingered me.

I'm wondering if it really was the food that reactivated my dick, or maybe it was just finally relaxing? Has anyone else run into this issue? And if so how do you balance not being super hungry and not feeling like a bowel movement might come?
