Was my ex an SSR?

i got my first bf when i was 18, at that time i was already super interested in x and my first time with him was like out of this world. i got so hooked i asked to do it every time we met which was almost everyday. i would come multiple times and idk what it was. im thinking it might be bc he lasted so long? (like i'm talking hourss and therefore thought it was the norm, recently found out its not :,) ) or maybe it was psychological since he had a very nice physique? or maybe he was just skilled? hell if i know

I finally had x again not too long ago, 2 years after said bf. but i was so surprised by how uninterested and bored i was. i was so disappointed but did it a few more times with this guy hoping i would eventually like it, but it was at most just aight. i never ohed.

how do i go about this? should i keep trying with other people? how rare is it that a guy last for longer than 25 min? what are the chances i find someone who is that good or am that compatible with? should i reach out and see if my ex would want to be fwb if he's single and interested?

what do i doooooo i'm having as great of a time solo but i miss the good x
