Ok k please answer on behalf of Thelma

usually when women become disinterested in sex it has to be the guy, or that she has been having extramarital affairs.

if its the guy, he is either
-impotent due to ejaculating too much. erectile powers all come from semen and hence semen retention is very important that guys shouldn't ejaculate everytime they have sex / masturbate.

-too much sexual fantasizing as a result of influence from porn

-demand too much sex and never connect body mind and soul, just bodily connection without any consideration over other aspects

-couldn't satisfy her and make her reach orgasmic gratification, in short, could be due erectile dysfunction

- too much foreplay and lack of prolonged penetrative sex everytime
