I'm getting anxiety attacks from not getting hard

Hey, (21m never dated)
So I was walking home. And passed a really cute girl. But nothing happened below at all.

(Backstory, I’ve stopped intense porn and hentai. I’m now suffering from anxiety attacks that when I end up with someone I won’t preform intercourse sex well)

I got home and was sat at my desk. And felt like trying to relax by masturbating. Got comfy. Mind already spinning with thoughts, but deep breaths, told myself I’m allowing this time for me, that this is ok to do. And started..

About 5 mins later and I have a full imaginary scenario playing in my head, you know.. but It didn’t get hard. Not once, tried altering my breathing a little, beep breaths to keep head clear, nothing. Started freaking out.

Reached for this app and did one libido booster, up immediately..did an erotica story and finished hard.

But now I’m sat here shaking, the process scaring me to the idea that when I get a woman.. if it dosnt go up in those scenarios..
