It went from erect to flaccid /u/Seek_Thy_Truth Sex

I am a 25 male and yesterday was my first time having sex. I have been watching porn and masturbating (went from watching straight to trans) for several years. Currently I am on the path of improving myself and abstaining from it. So, before I had sex yesterday, I had not masturbated for 3 weeks, I often watched porn but that’s about it. I had a girlfriend (5 years ago, been single since) who we engaged in foreplays and I got so hard and I wanted her so bad but I have never hd sex with her. So I decided to pay for a sex worker since I wanted to know how sex feels like and be actively engaged in relationships rather than using my own hand. I believe it’s a healthier way to live. So I was nervous, at first when I reached at her hotel, I hesitated. I had to contemplate for like 10 minutes before I decided to call her and meet her. I explained to her that it was my first time, she was surprised and thought that I had to be engaged in sexual relationships sooner. Anyways, at first she told me to lay down and relax. She played with my penis to erect it, so she could put on the condom. The erection was fast, because I was touching her all over because I wanted to feel what it’s like. The first I did the doggy her for some time (1 to 2 minutes) and that’s when everything changed. All that time I wasn’t feeling much. I was thinking if that’s what sex feels like. I started to lose my erection and after time I couldn’t get it up. She tried changing styles, touching me but I couldn’t. I asked her I could lay down for a while while she waits. I tried to get it up by thinking of things, but nothing worked. I just ended up paying her and leaving. I didn’t even cum. I was wondering, could there be something wrong with me because I have been masturbating my whole life and watching porn? But it has been 3 weeks since I have masturbated. I have no clue.
