Now its just a "if randf() < 0.15 && temparray.size() > 0:". My suggestion is like this "if randf() < (0.15+0.15*i.person.lewdness+0.15*i.person.lust) && temparray.size() > 0:" and on each generated request lewd/lust values will decrease. Just a eg.
This way the more lewd/lust partner will want more of action.
