Any mods that make it so Male NPC's and maybe even creatures have a orgasm limit depending on the amount of Sperm they have?

[Scarlet Queen]

Want to make it so they will only be able to have sex if they have enough cum to orgasm, maybe even the longer they went without cumming (Days) the bigger the orgasm.

[NymphoElf]

Sexlab Separate Orgasms has something vaguely like this, but it's not likely to do exactly what you want.

 

As far as orgasm volume, many mods tend to track their own variant of that, so that's going to be next to impossible unless you make yet another independent variant.
