I feel regret first

I just met up with some guy on Grindr it was my first gay experience he literually lives 3 doors down from me im 22 and hes 43. I showed up to his house we got naked he told me to lay on his bed so i did he starts sucking me, then i get horny af ask for water then i drink some and go to town on his cock, ive been wanting to do this for like 4 years. I popped up and down taking him all the way in sucking and licking his balls too. I did this for about 10 minutes then i told him to cum on my face. Now im laying in my bed thinking what the fuck did I just do and feel disgusted even though i kinda liked sucking on him for the oral fixation. IS THIS NORMAL?
