29 year old male. New here. masturbated 5-6 times a day.

My penis size is a little below average. Like size wouldn't be one of it's strength. And because of that awareness i was always anxious about meeting women. And the older i got, my anxiety grew. I used to only masturbate when i got an erection. It felt good and i did it when i could. Which wouldn't be so often as i wouldn't be alone by myself much of the time.
Slowly as i grew older i found myself having alone more often. but things started worsening since 2013. but even before 2013 there would be moments when i had a limp dick on my hands and still got off. Because from then on i had this room where i could just shut myself in with anyone bothering me. like a fort i could masturbate to. So it was about the same time i began smoking weed regularly. So both of, marijuana and masturbation started fusing. Like i started enjoying masturbation right after i smoked a joint.
The method in which i would masturbated also evolved into something weird. I wouldn't stroke it up and down. I would lay down on my stomach, keep a pillow to my side and rest my left shoulder on it. So that my body would be a little slanted. Then i would put my hand on my penis, position my index finger to touch the head and then i would just do an embarrassing press and release kind of movement to it. My penis needn't even be hard, a limp dick would be no problem to get an orgasm. and slowly what would take me about 5-10 minutes turned into a full 1 hour weird masturbation session. For about 5-6 times a day. One in the morning, one before lunch, one after lunch, one after my afternoon coffee, one before dinner and one after dinner. all after smoking a joint. My job is art and design so i can stay in my room all day aswell.
this went on. Slowly i started to seek someone real to have sex with. and dating app made it easier for a person with anxiety like me to find someone. So yesterday, i met with this girl, she was gorgeous. she told me that she found me very attractive. So we made out and i couldn't get my dick to be hard. I tried everything. But nope. We just lay there and started kissing, it felt a little turned on but my dick didn't erect. It didn't used to be like this. It was embarrassing and made me feel guilty that i couldn't pleasure a girl.
So from after that incident i kind of looked into it and it seems like i went inside this rabbit hole and had become seriously addicted to masturbation. 5-6 times normal, i just thought i had a bigger sex drive but, but that wouldn't result in a limp dick. I don't know. But from where i see, i see nothing more out of the ordinary from all the things i do apart from my excessive masturbation. so i haven't masturbated since yesterday and haven't looked at any porn. I am trying to get through with this the most effective way possible. I would be glad to hear what you all have got to say about this.
