I’m with you in this. I’ve talked to some of my friends about this and it sounds like 5-20% ish of people feel likewise.

To elaborate: I’ve very rarely felt endorphins from exercise. I’m in good shape, I’ve exercised a lot in the past (less so now), I even ran a marathon (not quickly).

After a short workout I do feel more awake and I like the bodily feeling of having exercised, but I’ve rarely felt any endorphin release during exercise which has pushed me forwards.

For example, the marathon I did was pure type 2 fun (fun in retrospect). However most runners I talk to say running is type 1 fun for them (fun at the time). Definitely not for me, it was miserable at the time.
