You can't argue with nature, no matter how hard we try. To increase the sexual activity of your sexual partner by reproaches and complaints is a futile task. There is such an index as the trochanter index; it defines your type of sexual constitution. If a couple has completely different indicators, do not try to change them. Unfortunately, it is unlikely to succeed. The need for sexual intercourse between partners should still be approximately equal. When I see that my girlfriend doesn't want sex, I find porn on the site link and jerk off. It's better than forcing my girlfriend.
