penis Penis don't get hard during sex

[leoprotoncio]

Hello everybody.  I have a problem during sex scenes, penis don´t get hard.  I don't understand why. Just one sim (the first one I created) has erections normally.  The rest of the sims have sex with their penis soft, dead.  I tried everything. Changing WW versions, installing DD, erasing Mods directory, erasing Sims 4 entire directory, and nothing changes.  I tried to clone my only one sim working correctly, but when i clone it, he has the same problem.  I even tried to modify it changing cloth or hair, and save it with another name, and happens the same.  I dont know what to do,
