It's been some time so here are a couple other games I found:
Lust Friend, lose during the first turn of battle for it to be counted as prematurely ejaculating. Succubus Puttel (not on this site) by the same devs also has this mechanic.
Echoes of Lust, you progress through sex scenes in this game based on your 'sexual experience' stat. Consequently, if it's too low you'll blast your load too early.
Thinking About You, there's a lust mechanic I can't really wrap my head around, but it has a chance to overflow in certain scenes depending on your actions and leads to MC prematurely cumming.
Artificial Academy 2, use sex positions where only the male cums and immediately end the sex after he does, the girl will mock/scold/tease/praise the guy for cumming by himself depending on her personality.
Honourable mention :
Nymphomania Priestess looks like it might have a sexual endurance stat and roll checks to determine if MC can last while fucking, but still too early in development to say for sure.
