another update about me (18m) being anxious about having sex as a virgin

posting on here is kind of a coping strategy for me whenever i worry about this so hopefully i'm not annoying to you guys

so it's actually been a few days since i listened to porn last and i actually think that's pretty good. i only did ever get turned on by the vanilla shit but everywhere i go i get the notion that porn has altered my brain permanently and that i should give up and i don't know how to not apply that to me. i'm a virgin and i'm worried if and when i have a sexual encounter i won't be able to stay hard or something because i got the wrong idea from the porn i listened to. a lot/most of the porn i listened to did include foreplay which turned me on but i still feel like i'll never truly be cured or that i'll have ED forever or something.

i already have conditions like GAD which can get pretty bad at times and i can tell you without a doubt that i'd be a nervous wreck during sex. this is because i'd worry i'd leave the other person unsatisfied, or that i hurt them because of something wrong i learned listening to porn. i'm really really not into the incest shit or BDSM or anything beyond vanilla. i just want slow and passionate shit with someone i care about deeply and i want them to feel loved and appreciated. that is all. i don't want to PIV jackhammer style with someone or whatever. i just want to feel some mutual love with somebody and i worry that the porn i listened to somehow killed all my chances of this ever happening successfully. i don't want to go into a relationship and have terrible sex and then someone leave me because of it or them leave me because i gave them self esteem issues.

that's it really and i really could use some insight or some reassurance that everything's gonna be ok, and if everything's not gonna be ok you can 100% say that too. thank you for reading if you made it this far and i hope you all are having a good day/night/evening :)
