Proposed to my gf of 5 years and now her sex drive has intensified

Context: we have had a healthy and good sex life this far into our relationship. Not super frequent or super adventures though. She suffers from feelings of inadequacy and a lack of empowerment due to her past relationships and family structure unit. Proposed the other day, she said YES!!! Since that day two weeks ago we have been having sex daily. Hot, adventurous and steamy sex. Last night she told me to “f*ck her however I want too”. Never had this experience with her. Feels surreal to me that putting a ring on her finger has changed her outlook and the way she perceives sex. Has anyone had a similar experience???
