So many things are involved: could be therez something u r not doing right down there , could b u finish sooner than she starts, or she wants to stay married to u but her heart belongs to one rugged guy that smooches her anywhere before fucking her even with her pants on, @ d kitchen, toilet/bathroom, parlour even in d balcony when no one z watching. We all need sexual satisfaction, if not from a partner, else where. Although she owes u a duty, spiritual and otherwise, to submit to you. N u r to love her.
Pls get to know her and know her very well.
Every likes sex, it depends on how and who u have it with for sexual happiness
