First time Grindr meet up

So today i met someone on grindr. We agreed that he will be top and i’ll be a bottom
Starting was good he sucked my nipples , squeezing them and my butt , he started fingering me really good and pushed me on the bed then stared licking my asshole
But……
He was unable to get hard🫣
But things still go on He fingered me really hard i was about to cum but he stopped cuz there was someone at his door and then we decided it for some other day.
