Kristin Cavallari and her boyfriend Mark Estes openly discussed their sex life on her podcast 'Let's Be Honest,' revealing that they consider each other the best sex they've ever had. Cavallari, 37, attributes improved sexual experiences to increased confidence and being more present as she ages. The couple, despite a 13-year age gap, shared insights on their chemistry and dismissed any need to fake orgasms. The candid discussion included playful exchanges and inquiries about sexual fantasies, though Cavallari refrained from sharing certain details publicly. Their relationship, which began earlier this year, has been publicly acknowledged on social media despite some criticism regarding their age difference.
