I don’t know what to do anymore…

I am a M mid 20s fit/athletic build and 3 weeks ago I hooked up with a 10/10 goth girl, it was one of the best nights ever, but right as I was going to cum she stuck her middle finger in my ass.

I came buckets and buckets… since this experience I have not masturbated or even had an urge and I used to almost every day. And tbh I havent really been hard, to fix it I stuck a finger in my ass barely and got hard asf again.

Idk if this happened to anyone before or what, but I want my cock working again lol
