18 year old stuck in a corner

Yo-
Just created this account for this post, so hopefully someone here has a shared experience and can offer some advice. I am recently 18, and I am a virgin. I have tried to fuck probably 5 times with the same girl, and every time my dick cannot get hard enough. I am very athletic, have no health problems to mine or my doctors knowledge, and am a good looking guy. I am in a friend group that is very open. This is a generation where hooking up is the norm, so everyone talks about what they do with other people as it would be abnormal not to. However, All of my friends fucking roast me for still being a virgin despite my attempts to have sex. Like in the worst situations. One of my best friends (who is very sexually experienced) even started saying "ED" and calling me a virgin at our groups dinner table at our school's formal, which everyone heard and was laughing about. I know I am giving them the reaction they want my getting mad and taking this personally, but it is about my personal life so fuck yeah im taking it that way. The fact that my virginity has become the butt of a lot of jokes for my friend group is completely degrading and embarrassing. I am pretty introspective, so I have assessed that this is a psychological issue, as I can jerk off to porn fine normally. This embarrassment is without question perpetuating my innability to maintain an erection with this girl, who happens to be fucking gorgeous and is definitely the most attractive girl in my friend group, making this whole thing even more nerve racking. I feel like hooking up with her has lost the intimacy due to the underlying desire to no longer be a virgin, which I think is more driven towards having my friends stop fucking with me at this point. Please toss me your two cents!!
